  DESCRIPTION = "
     A HISTORY object is a dynamic description of the history of
     one or more associated data objects in a file.  It
     supplements the essentially static description contained in
     the PDS label.
     The HISTORY object contains text in a
     format similar to that of the ODL statements used in the
     label.  It identifies previous computer manipulation of 
     the principal data object(s) in the file.  It includes an
     identification of the source data, processes performed,
     processing parameters, as well as dates and times of
     processing.  It is intended that the history be available
     for display, be dynamically extended by any process
     operating on the data, and automatically propagated to the
     resulting data file.  Eventually, it might be extracted for
     loading in detailed level catalogs of data set contents.
     The HISTORY object is structured as a series of History
     Entries, one for each process which has operated on the
     data.  Each entry contains a standard set of 
  ODL element
     assignment statements, delimited by GROUP = program_name
     and END_GROUP = program_name statements.  A subgroup in
     each entry, delimited by GROUP = PARAMETERS and END_GROUP =
     PARAMETERS, contains statements specifying the values of
     all parameters of the program.
     HISTORY ENTRY ELEMENTS
     Attribute       Description
     VERSION_DATE    Program version date, ISO standard format.
     DATE_TIME       Run date and time, ISO standard format.
     NODE_NAME       Network name of computer
     USER_NAME       Username.
     SOFTWARE_DESC   Program-generated (brief) description.
     USER_NOTE       User-supplied (brief) description.
     Unlike the above
     elements, the names of the parameters defined in the
     PARAMETERS subgroup are uncontrolled, and must only conform
     to the program.
     The last entry in a HISTORY object is
     followed by an END statement.  The HISTORY object, by
     convention, follows the PDS label of the file, beginning on
     a record boundary, and is located by a pointer statement in
     the label. There are no required elements for the PDS label
     description of the object; it is represented in the label
     only by the pointer statement, and OBJECT = HISTORY and
     END_OBJECT = HISTORY statements.
     The HISTORY capability
     has been implemented as part of the Integrated Software for
     Imaging Spectrometers (ISIS) system (see QUBE object
     definition).  ISIS Qube applications add their own entries
     to the Qube file's cumulative History object.  ISIS
     programs run under NASA's TAE (Transportable Applications
     Executive) system, and are able to automatically insert all
     parameters of their TAE procedure into the history entry
     created by the program.  Consult the ISIS System Design
     document for details and limitations imposed by that
     system.  (See the QUBE object description for further

     archive volume.  The INDEX table contains one row for each
     data file (or data product label file in the case where
     detached labels are used) on the volume.  The table is
     formatted so that it may be read directly by many data
     management systems on various host computers.  All fields
     (columns) are separated by commas, and character filesd are
     enclosed by double quotation marks.  Each record ends in a
     carriage return/line feed sequence.  This allows the table
     to be treated as a fixed length record file on hosts that
     support this file type, and as a normal text file on other
     hosts.  It is recommended that RECORD_BYTES and ROW_BYTES
     be even numbers to simplify ingestion of these files on
     systems where byte-level parsing is either difficult or
     impossible.  There are two categories of columns for an
     Index table:  Identification and Search.  PDS data element
     names should be used as column names wherever appropriate.
     The required columns are used for identification.  The
     optional columns are data dependent and are used for
     search.  For example, the following may be useful for
     searching:
      
     LOCATION (e.g., LATITUDE, LONGITUDE,ORBIT_NUMBER)
     TIME (e.g., START_TIME,SPACECRAFT_CLOCK_START_COUNT)
     FEATURE (e.g., FEATURE_TYPE)
     OBSERVATIONAL CHARACTERISTICS (e.g., INCIDENCE_ANGLE)
     INSTRUMENT CHARACTERISTICS (e.g., FILTER_NAMES)
      
     For archive volumes created before this standard was approved:
      
     1) If the keyword INDEX_TYPE is not present, the value defaults
     to SINGLE unless the Index's filename is given as CUMINDEX.TAB.
     2) If the keyword INDEXED_FILE_NAME is not present,
     the value defaults to '*.*' indicating that the index
     encompasses all files on the volume.
      
     The required COLUMN objects must be named (NAME=):
      
     FILE_SPECIFICATION_NAME OR PATH_NAME and FILE_NAME
     PRODUCT_ID (**)
     VOLUME_ID (*)

     PRODUCT_CREATION_TIME (*)
     LOGICAL_VOLUME_PATH_NAME (must be used with PATH_NAME and
     FILE_NAME for a logical volume) (*)
      
     (*)  If the value is constant across the data in the index
     table, this keyword can appear as a keyword inside the
     INDEX_TABLE object.  If the value is not constant, then a
     column of the given name must be used.
     (**) PRODUCT_ID is not required if it has the same value as
     FILE_NAME or FILE_SPECIFICATION_NAME.

     The QUBE object is a multidimensional array (called the
     core) of sample values in multiple dimensions. QUBEs of one
     to three dimensions can support optional suffix areas in
     each axis.
     A specialization of the QUBE object is the ISIS
     (Integrated Software for Imaging Spectrometers) Standard
     Qube, which is a three-dimensional QUBE with two spatial
     dimensions and one spectral dimension.  Its axes have the
     interpretations 'sample', 'line and 'band'.  Three physical
     storage orders are allowed: band-sequential,
     line_interleaved (band-interleaved-by-line) and
     sample_interleaved (band-interleaved-by-pixel).
     An example of a Standard ISIS Qube is a spectral
     image qube containing data from an imaging spectrometer.
     Such a qube is simultaneously a set of images
     (at different wavelengths) of the same target area,
     and a set of spectra at each point of the target area.
     Typically, suffix areas in such a qube are confined
     to 'backplanes' containing geometric or quality
     information about individual spectra, i.e. about
     the set of corresponding values at the same pixel location
     in each band.
     NOTE: The following required and optional
     elements of the Qube object are ISIS-specific.  Since the
     ISIS system was designed before the current version of the
     PDS Data Dictionary, some of the element names conflict
     with current PDS nomenclature standards.
     NOTE:  In a Generalized ISIS Qube, the axis names are
     arbitrary, but in a Standard ISIS Qube, the standard value
     set applies."

  NAME = SPECTRAL_QUBE
  STATUS_TYPE = APPROVED
  DESCRIPTION = "
     Note that the SPECTRAL_QUBE described here is specifically a PDS
     SPECTRAL_QUBE.  While similar to the ISIS Qube, it is not identical.
     (For guidelines on producing a spectral qube that is compliant with
     both PDS and ISIS, see the SPECTRAL_QUBE chapter of Appendix A of the
     PDS Standards Reference.)
      
     The SPECTRAL_QUBE object is a three-dimensional object with two
     spatial dimensions and one spectral dimension.  The axes have the
     interpretations 'sample', 'line', and 'band', respectively.
      
     Each of the three axes in a SPECTRAL_QUBE object may optionally
     include suffix data that extend the length of the axis.  Conceptually,
     this can be viewed as forming one or more suffix planes that are
     attached to the core qube.  Suffix planes that extend the band
     dimension are called BACKPLANES.  Suffix planes that extend the sample
     dimension are called SIDEPLANES.  Suffix planes that extend the line
     dimension are called BOTTOMPLANES.
      
     Note that these terms refer to the 'logical' axes -- that is, how the
     axes are conceptually modeled -- and are not necessarily related to
     the physical storage of the SPECTRAL_QUBE object.  The suffix planes
     are used for storing auxiliary data that are associated with the core
     data.  For example, a backplane might be used for storing the latitude
     values for each spatial-spatial pixel.  Another backplane might be
     used for storing the wavelength of the deepest absorption feature that
     was found in the spectrum at each spatial-spatial pixel.  One or more
     SIDEPLANES might be used for storing engineering data that are
     associated with each spatial line.
      
     Within the logical structure of the SPECTRAL_QUBE, SAMPLE=1 is the
     left edge of the spatial-spatial core image.  LINE=1 is the top edge
     of the spatial-spatial core image.  BAND=1 corresponds to the
     spatial-spatial images at the 'front' of the qube.  Core coordinates
     do not carry over to the suffix regions.
      
     The file in which a SPECTRAL_QUBE data object is stored is physically
     access as though it were a one-dimensional data structure.  Storing
     the SPECTRAL_QUBE thus requires that the 'logical' three-dimensional
     structure be mapped into the one-dimensional physical file structure.
     This involves moving through the three-dimensional structure in
     certain patterns to determine the linear sequence of core and suffix
     pixel values that occur in the file.  In SPECTRAL_QUBE files, this
     pattern is defined by specifying which axis index varies fastest in
     the linear sequence of pixel values in the file, which axis varies
     second fastest, and which axis varies slowest.
      
     In SPECTRAL_QUBE files, the names of the three axes are always SAMPLE,
     LINE, and BAND.  The AXIS_NAME keyword has an array of values that
     list the names of the axes in the qube.  The order of the names
     specifies the qube storage order in the file.  The first axis is the
     fastest varying, and the third axis is the slowest varying.  The
     SPECTRAL_QUBE supports the following three storage order:
      
     - (SAMPLE, LINE, BAND) - Band Sequential (BSQ)
     - (SAMPLE, BAND, LINE) - Band Interleaved by Line (BIL)
     - (BAND, SAMPLE, LINE) - Band Interleaved by Pixel (BIP)
      
     The lengths of the core axes are given by the CORE_ITEMS keyword and
     the lengths of the suffix axes are given by the SUFFIX_ITEMS keyword.
     Both these keywords have array values, whose order corresponds to the
     order of the axes given by the AXIS_NAME keyword.
      
     In the physical file storage, suffix pixel data (if present) are
     interspersed with the associated core pixel data.  For example, in a
     BSQ storage order file, the physical qube storage in the file begins
     with the pixels in the first (top) line of the spatial-spatial image
     plane at the first wavelength band.  This is followed by the sideplane
     pixel values that extend this line of core pixels.  Next are the core
     pixels for the second line, followed by the sideplane pixels for the
     second line.  After the last line of this first core image plane (and
     its associated sideplane pixels) comes the bottomplane pixels
     associated with the first band.  This is then repeated for the second
     through last bands.  Finally, all the backplane data are stored after
     all the core data and associated sideplane and bottomplane pixels.
      
     If a SPECTRAL_QUBE file includes suffixes on more than one axis, then
     the region that is the intersection between two (or all three) of the
     suffix regions is called a CORNER region.  The PDS requires that space
     for CORNER region data be allocated in the data files.  However, this
     space is never actually used.
      
     In a SPECTRAL_QUBE file, core pixels can occupy one, two or four
     bytes.  All core pixels within a single file must be of the same
     physical storage size.  Suffix pixels can also occupy one, two, or
     four bytes of storage in the file.  All the suffix pixels within a
     single file must be of the same physical storage size.  Suffix pixels
     need not be the same size as core pixels.  Handling of different pixel
     data types is described in detail below.
      
     In SPECTRAL_QUBE files, core pixel values can be represented by one of
     several formats.  The formats available are dependent on the number of
     bytes used to store the values in the file.  The format is given by
     the CORE_ITEM_TYPE keyword and the number of bytes stored is given by
     the CORE_ITEM_BYTES keyword.  The following table shows the allowable
     formats and the number of bytes of storage the use:
      
     CORE_ITEM_BYTES     CORE_ITEM_TYPE    Type Conversion
                                             Parameters
       1, 2, or 4       UNSIGNED_INTEGER        Yes
       1, 2, or 4     MSB_UNSIGNED_INTEGER      Yes
       1, 2, or 4     LSB_UNSIGNED_INTEGER      Yes
       1, 2, or 4           INTEGER             Yes
       1, 2, or 4         MSB_INTEGER           Yes
       1, 2, or 4         LSB_INTEGER           Yes
            4              IEEE_REAL             No
            4               VAX_REAL             No
            4               PC_REAL              No
      
     As the table above indicates, stored integer values can be converted
     to real values, representing the actual pixel.  The type conversion
     parameters are given by the CORE_BASE and CORE_MULTIPLIER keywords,
     and the real value being represented is determined as follows:
      
       'real_value' = CORE_BASE + (CORE_MULTIPLIER * REAL(stored_value))
      
     For 4-byte real formats, the stored values are floating point values
     that directly represent the pixel values.
      
     The same data types and number of storage bytes that are shown in the
     above table are also available to suffix pixels.  However, suffix
     pixels need not be the same size or have the same data type as the
     core pixels.  Therefore, there is a SUFFIX_ITEM_BYTES keyword to
     indicate the number of bytes stored for suffix pixels and a
     SUFFIX_ITEM_TYPE keyword to describe the data type of the suffix
     pixels.  Each suffix plane within a single file can have a different
     data format.  Thus, the values of these keywords are arrays.  Each
     element of the array refers to a separate suffix plane.
      
     The SPECTRAL_QUBE allows the number of bytes used to store data in
     each suffix pixel (SUFFIX_ITEM_BYTES) to be less than the total number
     of bytes allowcated to each suffix pixel (SUFFIX_BYTES).  It is
     therefore necessary to describe how the stored bytes are aligned
     within the allocated bytes.  The BIT_MASK keyword is used for this
     purpose.
      
     Note that in the following list of required and optional objects and
     groups, while the *_SUFFIX groups are listed as optional, they are
     required if their named axis appears in the qube."

     ancillary data needed to support the planning and subsequent
     analysis of space science observations.
     The SPICE system includes the software and documentation
     required to read the SPICE kernels and use the data
     contained therein to help plan observations or interpret
     space science data.  This software and associated
     documentation are collectively called the NAIF Toolkit.
     Kernel files are the major components of the SPICE system.
     The EPHEMERIS kernel type (SPK) contains spacecraft and
     planet, satellite or other target body ephemeris data
     that provide position and velocity of a spacecraft as a
     function of time.  The TARGET_CONSTANTS kernel type (PCK)
     contains planet, satellite, comet or asteroid cartographic
     constants for that object.  The INSTRUMENT kernel type (IK)
     contains a collection of science instrument information,
     including specification of the mounting alignment, internal
     timing, and other information needed to interpret
     measurements made with the instrument.  The POINTING kernel
     type (CK) contains pointing data (e.g., the inertially
     referenced attitude for a spacecraft structure upon which
     instruments are mounted, given as a function of time).
     The EVENTS kernel type (EK) contains event information
     (e.g., spacecraft and instrument commands, ground data
     system event logs, and experimenter's notebook comments).
     The LEAPSECONDS kernel type (LSK) contains an account of the
     leapseconds needed to correlate civil time (UTC) with
     ephemeris time (TDB).  This is the measure of time used in
     the SP kernel files.  The SPACECRAFT CLOCK COEFFICIENTS

  STATUS_TYPE = APPROVED
  DESCRIPTION = "
     The WINDOW object is used to identify an area of interest within an
     IMAGE object.  For example:
      
       - In sparse images, a sub-image would indicate where the valid data
         are located.
      
       - In mosaicked images, sub-images could indicate the borders of the
         constituent images.
      
       - In approach images, a sub-image could indicate the area where the
         target is expected to be found.
      
     The WINDOW object identifies a rectangular area of interest within an
     IMAGE object.  WINDOW objects may not serve as the primary object in a
     data product, nor may they appear outside the context of an IMAGE
     object.  The areas described by separate WINDOW objects may overlap in
     whole or in part, but WINDOW object definitions may not be nested.
      
     The boundaries and physical attributes of the WINDOW object are always
     determined with reference to the enclosing (parent) IMAGE object.
     That is, 'first' is defined with respect to the LINE_DISPLAY_DIRECTION
     and SAMPLE_DISPLAY_DIRECTION of the IMAGE and the WINDOW must have the
     same SAMPLE_TYPE and SAMPLE_BITS as the IMAGE.  WINDOW objects may not
     have prefix or suffix bytes.

          The CITATION_DESC contains a citation for the product or
          DATA_SET_INFORMATION object in which it appears. It provides
          a string that may be used to cite the product (data set) in a
          publication. It should follow the standard citation order as
          outlined in Appendix B, Section 31.5.5.3.1 of the PDS Standards
          reference, which in turn follows established practice for
          scientific journals that cite electronic publications
          (e.g., AGU Reference citation format).
      
          The CITATION_DESC must contain sufficient information to locate
          the product or data set in the PDS archives.  For example,
          the CITATION_DESC in a DATA_SET_INFORMATION object must contain
          the DATA_SET_ID; it will also likely contain VOLUME_ID information
          for the archive volumes, an author list, a release date, and so
          on as appropriate.
      
          Note that if CITATION_DESC is used within any product label within
          a data set, all product labels within that data set must also have
          a CITATION_DESC, even if they are only filled with 'N/A'.

     number of digits in a date.  Usually DATE(6) (YYYY-MM) or
     DATE(8) (YYYY-MM-DD).  TIME(X) where X is the number of
     digits in a time statement.  This is usually represented as
     TIME(6) (HH:MM:SS) or TIME(4) (HH:MM)>  DATETIME is used
     for UTC system format date-times (MM-DD-YYYYTHH:MM:SS.HHH). JUSTLEFT is
     used for left-justified character strings, and JUSTRIGHT is
     used for right justification.  DIGIT(X) is used where X is
     the number of digits in an integer, so 897 would be
     DIGIT(3).  SCI(X,Y) is used where X is the number of
     significant digits before the decimal in scientific
     notation, and Y is the number following the decimal, so
     1.293E-2 would be SCI(1,3).  FLOAT(X) is used where X is the
     total number of digits in a floating point number, so
     33.018746 would be FLOAT(8).  USDOLLAR is used for monetary
     amounts in the indicated currency, PHONE is used for
     telephone numbers, and FTSPHONE is used for seven-digit
     numbers in the Federal Telephone System."

     The file_state element indicates whether a cube file possibly contains
     potentially corrupted data. Note: This keyword element is derived directly
     from the USGS' ISIS software keyword element of the same name. The
     following is a direct description of this keyword element from the ISIS
     software documentation. : 'The I/O for ISIS cube files and table files is
     buffered, i.e., part of the data for a file is held in memory and is not
     actually written to the file until the file is closed. This improves
     processing efficiency. However, when a new file is opened for creation or
     an existing file is opened for update (Read/Write) access, the file will
     not be properly closed if a system crash occurs or if the program is
     aborted (either due to a program malfunction or due to user action). This
     results in a possibility that the file contains corrupted data. When this
     happens, the FILE_STATE label keyword is set to 'DIRTY' and most ISIS
     applications normally refuse to process this potentially corrupted data.
      
     ISIS includes a keyword called FILE_STATE in every ISIS cube (qube), table,
     and Instrument Spectral Library (ISL) data file. This keyword will be set
     to either CLEAN or DIRTY. Each time the cube is opened this keyword will be
     checked. If the FILE_STATE is equal to CLEAN, then the program will
     continue on normally. However, if the FILE_STATE is DIRTY, then the
     application will halt with the appropriate error message.
      
     When a FILE_STATE becomes DIRTY, it indicates that something has gone wrong
     in a previously run application. ISIS will always set the FILE_STATE to
     DIRTY when the file is being opened for writing. If the application crashes
     and does not close the cube properly the FILE_STATE will remain DIRTY.
      
     However, this does not always mean the file is corrupt. To help restore a
     file from DIRTY to CLEAN, ISIS has an application called 'cleanlab'.
     'cleanlab' will modify the FILE_STATE keyword in the label to a CLEAN
     state. This program should be used with caution as the contents of the file
     may not be valid when an ISIS file is left in a DIRTY state."

     The INSTRUMENT_ELEVATION element provides the value for the instrument's

     sense, it is primarily intended for use in surface-based instruments that
     measure pointing in terms of azimuth and elevation. When in a
     DERIVED_GEOMETRY group, defines the elevation (vertical rotation) at which
     the instrument is pointed. This value is expressed using the cooridinate
     system referred to by REFERENCE_COORD_SYSTEM_NAME and
     REFERENCE_COORD_SYSTEM_INDEX contained within the same group. The
     interpretation of exactly what part of the instrument is being pointed is
     mission-specific. It could be the boresight, the camera head direction, the
     CAHV camera model A vector direction, or any of a number of other things.
     As such, for multimission use this value should be used mostly as an
     approximation, (e.g., identifying scenes which might contain a given

     The desire to work with solar days, hours, minutes, and seconds of

     The FMS is defined as a point that moves on the celestial equator of
     a planetary body at a constant rate that represents the average mean
     motion of the Sun over a planetary year.  Local mean solar time, or
     LMST, is defined, by analogy with LTST, as the difference between the
     areocentric right ascensions of a point on the surface and of the
     FMS.  The difference between LTST and LMST varies over time.  The
     length of a mean solar day is constant and can be computed from the
     mean motion of the FMS and the rotation rate of a planet. The mean
     solar day is also called a 'sol'.  Mean solar hours, minutes, and
     seconds are defined in the same way as the true solar units.

  DESCRIPTION = "
     The LOCAL_TRUE_SOLAR_TIME element describes the local true solar time, or
     LTST.  It is one of two types of solar time used to express the time of day
     at a point on the surface of a planetary body. LTST is measured relative to
     the true position of the Sun as seen from a point on the planet's surface.
     The coordinate system used to define LTST has its origin at the center of
     the planet. Its Zaxis is the north pole vector (or spin axis) of the
     planet. The X-axis is chosen to point in the direction of the vernal
     equinox of the planet's orbit. (The vernal or autumnal equinox vectors are
     found by searching the planetary ephemeris for those times when the vector
     from the planet's center to the Sun is perpendicular to the planet's north
     pole vector. The vernal equinox is the time when the Sun appears to rise
     above the planet's equator.) Positions of points in this frame can be
     expressed as a radius and areocentric 'right ascension' and 'declination'
     angles. The areocentric right ascension angle, or ARA, is measured positive
     eastward in the equatorial plane from the vernal equinox vector to the
     intersection of the meridian containing the point with the equator.
     Similarly, the areocentric declination is the angle between the equatorial
     plane and the vector to the point. LTST is a function of the difference
     between the ARAs of the vectors to the Sun and to the point on the planet's
     surface. Specifically, LTST = (a(P) - a(TS)) * (24 / 360) + 12 where, LTST
     = the local true solar time in true solar hours a(P) = ARA of the point on
     the planet's surface in deg a(TS) = ARA of the true sun in degThe
     conversion factor of 24/360 is applied to transform the angular measure in
     decimal degrees into hours-minutes-seconds of arc. This standard
     representation divides 360 degrees into 24 hours, each hour into 60
     minutes, and each minute into 60 seconds of arc. The hours, minutes, and
     seconds of arc are called 'true solar' hours, minutes, and seconds when
     used to measure LTST. The constant offset of 12 hours is added to the
     difference in ARAs to place local noon (12:00:00 in hours, minutes,
     seconds) at the point where the Sun is directly overhead; at this time, the
     ARA of the true sun is the same as that of the surface point so that a(P) -
     a(TS) = 0. The use of 'true solar' time units can be extended to define a
     true solar day as 24 true solar hours. Due to the eccentricity of planetary
     orbits and the inclination of orbital planes to equatorial planes
     (obliquity), the Sun does not move at a uniform rate over the course of a
     planetary year. Consequently, the number of SI seconds in a true solar day,
     hour, minute or second is not constant. See also LOCAL_MEAN_SOLAR_TIME.
     (Definition adapted from [VAUGHAN1995].) This element replaces the older
     MPF_LOCAL_TIME, which should no longer be used."

  DESCRIPTION = "
        The MD5 algorithm takes as input a file (message) of arbitrary length
        and produces as output a 128-bit 'fingerprint' or 'message digest' of
        the input. It is conjectured that it is computationally infeasible to
        produce two messages having the same message digest, or to produce
        any message having a given prespecified target message digest. The
        MD5 algorithm is intended for digital signature applications.
      
        The MD5 algorithm is designed to be quite fast on 32-bit machines. In
        addition, the MD5 algorithm does not require any large substitution
        tables; the algorithm can be coded quite compactly.
      
        Most standard MD5 checksum calculators return a 32 character
        hexadecimal value containing lower case letters. In order to
        accomodate this existing standard, the PDS requires that the value
        assigned to the MD5_CHECKSUM keyword be a value composed of lowercase
        letters (a-f) and numbers (0-9). In order to comply with other standards
        relating to the use of lowercase letters in strings, the value must be
        quoted using double quotes.
      
      
        Example:  MD5_CHECKSUM = '0ff0a5dd0f3ea4e104b0eae98c87f36c'
      
        The MD5 algorithm is an extension of the MD4 message-digest algorithm
        1,2]. MD5 is slightly slower than MD4, but is more 'conservative' in
        design. MD5 was designed because it was felt that MD4 was perhaps
        being adopted for use more quickly than justified by the existing
        critical review; because MD4 was designed to be exceptionally fast,
        it is 'at the edge' in terms of risking successful cryptanalytic
        attack. MD5 backs off a bit, giving up a little in speed for a much
        greater likelihood of ultimate security. It incorporates some
        suggestions made by various reviewers, and contains additional
        optimizations. The MD5 algorithm has been placed in the public domain
        for review and possible adoption as a standard.
      
        For OSI-based applications, MD5's object identifier is
      
        md5 OBJECT IDENTIFIER ::=
          iso(1) member-body(2) US(840) rsadsi(113549) digestAlgorithm(2) 5}
      
        In the X.509 type AlgorithmIdentifier [3], the parameters for MD5
        should have type NULL.
      
        The MD5 algorithm was described by its inventor, Ron Rivest of
        RSA Data Security, Inc., in an Internet Request For Comments
        document, RFC1321 (document available from the PDS).

     12 to 8 bit compression algorithm (0-7) used to compress images from
     12 to 8 bits. Whether this option is enabled is indicated by MESS:COMP12_8.
     The compression is implemented using one of eight lookup tables, which are
     optimized to the lower WAC CCD read noise and higher NAC read noise, light
     levels, and bias level (nominal or after inflight drift):
      
     0 = Lo-noise hi-bias SNR proportional.  Case: Either NAC or WAC, for
     nominal bias (all DNs greater than 12-bit 230).  Formulation: Maps
     12-bit DNs between bias and saturation into 8 bits, proportional to SNR.
     Information loss is spread evenly over dynamic range.  Usage: Typical
     imaging with varied brightness.
      
     1 = Lo-noise hi-bias DN-weighted SNR proportional. Case: Low-noise (WAC)
     CCD, bias nominal (all DNs greater than 12-bit 230). Formulation: Maps 12
     bits between bias and saturation into 8 bits proportional to sliding scale.
     Information is preferentially retained at the low DN end. Usage: Faint
     objects. Saturates at a DN of 3000.
      
     2 = Hi-noise hi-bias DN-weighted SNR proportional. Case: High-noise (NAC)
     CCD, bias nominal (all DNs greater than 12-bit 230). Formulation: Maps 12
     bits between bias and saturation into 8 bits proportional to sliding
     scale.  Information is preferentially retained at the low DN end.
     Usage: B/W, mostly low brightness.
      
     3 = Lo-noise med-bias SNR proportional. Case: Either CCD, assuming bias
     has dropped tens DN (all DNs greater than 12-bit 180).  Formulation:
     Maps 12-bit DNs between bias and saturation into 8 bits, proportional to
     SNR. Information loss is spread over dynamic range. Usage:
     Typical imaging, varied brightness.
      
     4 = Lo-noise med-bias DN-weighted SNR proportional. Case: Lo-noise (WAC)
     CCD, assuming bias has dropped tens DN (all DNs greater than 12-bit 180).
     Formulation: Maps 12 bits between bias and saturation into 8 bits
     proportional to sliding scale. Information retained at low DN end.
     Usage: Faint objects.  Saturates at a DN of 3000.
      
     5 = Hi-noise med-bias DN-weighted SNR proportional. Case: High-noise (NAC)
     CCD, assuming bias has dropped tens DN (all DNs greater than 12-bit 180).
     Formulation: Maps 12 bits between bias and saturation into 8 bits
     proportional to sliding scale. Information is retained preferentially at
     the low end of the DN range. Usage: B/W, mostly low brightness.
      
     6 = Zero-bias SNR proportional. Case: Contingency; assuming bias
     decreased to near 0 from the nominal 230 12-bit DNs.
     Formulation: Maps 12-bit DNs between bias and saturation into 8 bits,
     proportional to SNR. Information loss is spread over the dynamic range.
     Usage: Typical imaging, varied brightness.
      
     7 = Linear. Case: either CCD, bias or read noise. Formulation: Maps 12-bit
     DNs between the bias level and saturation linearly into 8-bit space.
     Usage: High brightness mapping; information loss greatest at low DNs,
     preserves information at high DNs."

     A resolver provides a position reading of the pivot platform. The
     resolver only covers 45 degrees of motion; the resolver read-out values
     repeat eight times over the entire 360 degrees that an unconstrained
     platform could travel.  The DPU software must determine in which of the
     eight octants the platform is located before the resolver reading is
     meaningful.  The software combines the octant with the resolver reading
     to form a position that covers the entire 360 degrees.
      
     To determine the octant the DPU software must be commanded to 'home'
     the platform.  To home the pivot platform, the software drives the
     motor open loop backwards into the hard stop at -185 degrees.  Then
     the software drives the motor forward, open loop, prepositioning it to
     -179 degrees.  Until homing is completed, the pivot platform is
     considered 'lost' and all other pivot commands will remain pending.

     The MRO:THERMAL_CORRECTION_MODE element describes whether and what

     and thermal emission of the Martian surface. Three algorithms are
     available to perform an approximate removal of the thermal emission,
     to isolate solar reflectance. OFF indicates that no correction is
     performed. Data may be in units of radiance, I_OVER_F, or
     LAMBERT_ALBEDO. For any other choice, data are in units of
     LAMBERT_ALBEDO. CLIMATOLOGY;ADR_CL indicates that a predicted
     temperature for the correction was derived from a low spatial
     resolution climatic model contained in an Ancillary Data Record (ADR)
     with the string CL in the file name.
      
     EMPIRICAL_MODEL_FROM_SPECTRUM;ALG_M indicates that temperature for
     the correction was estimated empirically from measured CRISM
     I_OVER_F at long wavelengths. PHYSICAL_MODEL;ADR_TE indicates that
     a predicted temperature for the correction was derived using
     information on surface physical properties from a companion DDR,
     and a model of thermal emission contained in an ADR with the string
     CL in the file name.

     The IRAS satellite has a natural but non-standard coordinate system
     defined by SOLAR_ELONGATION and OBSERVATION_INCLINATION.  SOLAR_ELONGATION
     is the angle between the line of site of the satellite and the Sun.
     OBSERVATION_INCLINATION is the angle between the ecliptic plane and the

     the azimuth angle about the Earth-Sun axis). The value is zero when IRAS
     looks at the ecliptic plane in the direction opposite to the motion of the
     Earth around the Sun. The value increases clockwise around the Earth-Sun
     axis when facing the Sun, and opposite from the direction of the motion of
     the satellite in its polar orbit about the Earth.  OBSERVATION_INCLINATION
     is related to IRAS_CLOCK_ANGLE by the equation
     OBSERVATION_INCLINATION = 90 - IRAS_CLOCK_ANGLE.

  DESCRIPTION = "
            The QUATERNION element specifies a quaternion, which is a
     four-component representation of a rotation matrix.  This particular
     definition is focused on the PDS use of quaternions; one should refer
     to other sources for a more complete discourse on quaternion math.
      
     A quaternion may be used to specify the rotation of one Cartesian
     reference frame--sometimes referred to as the base frame or the
     'From' frame--into coincidence with a second Cartesian reference
     frame--sometimes referred to as the target reference frame or the
     'To' frame. Unlike an Euler rotation where three sequential rotations
     about primary axes are used, a quaternion rotation is a single
     action, specified by a Cartesian vector used as the positive axis of
     the rotation (right hand rule) and the magnitude (an angle) of
     rotation about that axis.
      
     The quaternion may be thought of as defining the instantaneous
     orientation--sometimes called 'pointing'--of a structure such as an
     instrument, antenna, solar array or spacecraft bus, given relative to
     a specified reference frame (the base frame), at an epoch of interest.
      
     Perhaps of more use is the concept that a quaternion may be used to
     rotate an arbitrary Cartesian 3-vector defined in one reference frame
     (e.g. an instrument's reference frame) to an equivalent vector
     defined in another reference frame (e.g. the frame tied to a
     spacecraft or the J2000 inertial reference frame).
      
     A quaternion has four components.  One of the components is a scalar,
     a function of the angle of rotation (cosine of half the rotation
     angle), while the remaining three components are used to specify a
     vector, given in the base reference frame, about which the rotation
     will be made. In the PDS context a quaternion has a magnitude of one,
     and so may be treated as a unit quaternion.
      
     In many cases a time tag (epoch) must be associated with the
     quaternion because the orientation varies over time. A time tag is
     not needed if the 'To' and 'From' frames have a fixed offset.
      
     The QUATERNION_DESC element is always to be paired with the
     QUATERNION element, and will contain a complete description of the
     formation and rotational sense of the quaternion specified with the
     QUATERNION keyword, and the structure (organization of the four
     components) of the quaternion.
      
     In the lingo of the NASA 'SPICE' ancillary information system a
     rotation matrix is synonymous with a C-matrix--that which may be
     obtained from a C-kernel. The SPICE Toolkit provides an assortment of
     routines that deal with quaternions. The SPICE system also provides
     information about specification of reference frames and time tags
     suitable for use with quaternions in the SPICE context. The NAIF Node
     of the PDS can provide additional documentation on quaternions in a
     spacecraft ancillary data context ('Rotations Required Reading' and
     'SPICE Quaternion White Paper')."

  DESCRIPTION = "
            The QUATERNION_DESC element is a pointer to an accompanying
     quaternion description file used to describe the formation rules for
     the quaternion and the specific rotation accomplished by application
     of that quaternion. This keyword is required to be used in
     conjunction with the QUATERNION keyword. The file to which this
     keyword points is to be included in the /doc subdirectory of an
     archive product.  This particular definition is focused on the PDS
     use of quaternions.
      
     In typical space science usage (and especially within the SPICE
     context) a quaternion is used to rotate a Cartesian 3-component
     position vector given in one reference frame (the 'From' frame) to a
     second frame (the 'To' frame).
      
     The quaternion description file must clearly provide three pieces of
     information. These items are as follows.
      
        1) Define the structure or organization of the quaternion: specify
     which component provides the angle of rotation and which three
     components specify the vector about which the rotation is to occur.
     It is best if this description includes the actual equations used to
     form a rotation matrix from the quaternion elements being specified.
     As an example, in the SPICE context, the equations for forming a
     rotation matrix (a C-matrix) from the four quaternion elements are:
      
                 +-                                                          -+

        2) Provide a clear, unambiguous identification (and mathematical
     specification, if not readily available elsewhere) of the base frame
     (the 'From' frame) in which an input vector is given;
      
        3) Provide a clear, unambiguous identification (and mathematical
     specification, if not readily available elsewhere) of the target
     frame (the 'To' frame) into which the input vector will be rotated by
     direct application of the quaternion.
      
     It is strongly suggested that equations showing how to apply the
     rotation matrix derived from the quaternion be provided.  As an
     example, in the SPICE system:
      
     A C-matrix is a 3x3 matrix that transforms Cartesian coordinates
     referenced to a ``base frame'' to coordinates in a target frame,
     which is often a frame fixed to an instrument, antenna, or other
     spacecraft structure for which knowing the orientation ('the
     pointing') is important.
      
     The C-matrix transforms coordinates as follows: if a vector v has
     coordinates ( x, y, z ) in some base reference frame (like J2000),
     then v has coordinates ( x', y', z' ) in instrument-fixed
     coordinates, where
      
      
             [          ] [ x ]     [ x']
             | C-matrix | | y |  =  | y'|
             [          ] [ z ]     [ z']
      
      
      
     With regards to the quaternion structure issue, unlike for some
     geometric quantities there is no standard for how to form a
     quaternion. Two formation rules are in common use (see below), and it
     is strongly suggested that users pick one of these.  But whatever is
     the rule being used in the particular instance must be carefully
     noted in the QUATERNION_DESC file.
      
     In the descriptions below, one system defines the four components
     with indices of 0 through 3. The other system uses indices 1 through
     4. The use of one or the other numbering system is not important, but
     the two schemes are shown here to be consistent with other
     documentation or SPICE code that the user may encounter.
      
     The first system defines components zero through three, with the 0th
     component as the scalar, and the 1st, 2nd and 3rd the vector
     components, where q0 = cos(a/2), q1 =-sin(a/2)*u1, q2 = -sin(a/2)*u2,
     q3 = -sin(a/2)*u3, where a is the angle (radians) representing the
     magnitude of the rotation, and u1, u2, u3 are components of the unit
     vector representing the axis of rotation. The order of the components
     in the QUATERNION keyword would be ( q0, q1, q2, q3 ) under this
     system.  This is the structure employed in SPICE C-Kernels and
     Toolkit subroutines, and is therefore the PDS recommended structure.
     The SPICE Toolkit provides an assortment of routines that deal with
     quaternions.
      
     The second system defines components one through four, with the
     fourth component as the scalar, and the 1st, 2nd and 3rd as the
     vector components, where q1 = sin(a/2)*u1, q2 = sin(a/2)*u2, q3 =
     sin(a/2)*u3, q4 = cos(a/2), where a is the angle (radians)
     representing the magnitude of the rotation, and u1, u2, u3 are
     components of the vector representing the axis of rotation. The order
     of the components in the QUATERNION keyword will be ( q1, q2, q3, q4
     ) under this system.  This is the structure often found in spacecraft
     telemetry.
      
     The equations for forming a rotation matrix from the four quaternion
     elements as defined in this alternate scheme are:
      
                 +-                                                          -+

                 |                                                            |

                 |                                                            |
                 |                                                            |
                 |                                                    2    2  |

                 |                                                            |
                 +-                                                          -+
      
      
     The rotation matrix transforms coordinates as follows: if a vector v
     has coordinates ( x, y, z ) in some base reference frame (like
     J2000), then v has coordinates ( x', y', z' ) in instrument-fixed
     coordinates, where
      
      
             [          ] [ x ]     [ x']
             |   ROT    | | y |  =  | y'|
             [          ] [ z ]     [ z']
      
     (With ROT defined as shown above, this equation transforming a vector
     in the base frame to a vector in the target frame is the same as
     shown earlier for the SPICE-style quaternions. The name CMAT has been
     replaced with the name ROT to help emphasize that this second system
     is NOT what is used within SPICE.)"

     in data_set_desc, as a shorthand notation of a document
     reference.
     The reference_key_id element is composed according to the
     following guidelines:
     1.  if there is an author for the publication, the general
     rule is:
       REFERENCE_KEY_ID = <author's last name><year><letter>,
          where
          <author's last name> is a maximum of 15 characters,
               and may need to be truncated.
          <year> is 4 characters for the year published.
          <letter> is optional but consists of one character
                used to distinguish multiple papers by the
                same author(s) in the same year.
        The following variations apply:
        a.  If there is one author:
         <author's last name><year>
         Example value:  SCARF1980
        b.  If there are two authors:
         <first author's last name>&<second author's last name>
         <year>
         Example value:  SCARF&GURNETT1977
       c . If there are three or more authors:
         <first author's last name>ETAL<year>
         Example value:  GURNETTETAL1979
        d.  If one author has the same last name as another:
         <author's last name>,<author's first initial>
         <year published>
         Example value:  FREUD,A1935
        e.  If the same author(s) published more than one paper
         in the same year:
           <author's last name><year><letter>
           or
           <first author's last name>&<second author's last name>
           <year><letter>
           or
           <first author's last name>ETAL<year><letter>
         Example values:  SCARF1980A
                          SCARF&GURNETT1977B
        f.  In cases where an initial reference has been
         catalogued and published on an Archive medium and
         subsequent references for the same author and same
         year are needed at a later date, the following rule
         applies:
         Leave the original reference as is, and add a letter
         to the subsequent references starting with the letter
         'B' since the original reference will now be assumed
         to have an implicit 'A'.  For example:  PFORD1991,
         PFORD1991B.
         Note that if the initial reference has only been
         catalogued and not yet published, then it can be
         modified such that the 'A' is explicit, i.e.
         PFORD1991A.
     2.  If there is no author for the publication, the general
     rule is:
      REFERENCE_KEY_ID = <journal name><document identification>
      where
      <journal name> is a maximum of 10 characters, and
           may need to be abbreviated
      <document identification> is a maximum of 10
           characters.  This id may consist of a volume number,
           and/or document or issue number, and/or year of
           publication.

     The reference point may be, for example, the center of a body, a
     standard star, or a specific location on a body or the celestial
     sphere.  This keyword should be used to define what the reference
     point is, logically or physically.  The REFERENCE_POINT_INDEX
     keyword describes the location of the reference point in units of
     axis index, while the REFERENCE_POINT keyword gives the same
     location in the physical units of the indices."

OBJECT = ELEMENT_DEFINITION

  STATUS_TYPE = APPROVED
  GENERAL_DATA_TYPE = REAL

  DESCRIPTION = "
     The REFERENCE_POINT_INDEX keyword is used to give the precise
     location of a reference point (center of a body, standard star,
     coordinate system reference point, etc.) relative to the origin
     of the associated object - typically an IMAGE or ARRAY.  The
     location is expressed as a sequence of values in units of the
     axis index, in the same order as the defined axes.  The indices
     for each axis are assumed to be numbered positively from 1.
      
     Although the indices are integral, the REFERENCE_POINT_INDEX
     values are floating point and may be expressed to an appropriate
     level of precision.  For example, if the reference point is the
     location of the center of a target body and known to sub-pixel
     accuracy, then it may have a REFERENCE_POINT_INDEX value that
     looks like: (215.678, 500.234).
      
     Note that the reference point is a logical concept, and thus is
     not required to be inside the associated object.  If, for example,
     the reference point described for an IMAGE object is outside the
     field of view included in the IMAGE, the values for
     REFERENCE_POINT_INDEX are determined by extrapolation of the image
     axes.  In this case some of the REFERENCE_POINT_INDEX values may be
     negative or greater than the maximum index found in the image.
      
     The REFERENCE_POINT_INDEX as defined here is analogous to the CRPIXn
     values of the FITS standard.  Users should note that the CRPIXn
     standard is often re-interpreted by data preparers, and should not
     assume that any particular CRPIXn set of numbers will map directly
     to a valid REFERENCE_POINT_INDEX without first verifying the local
     use of the CRPIXn keywords.
      
     The REFERENCE_POINT_DESC keyword should be used in conjunction with
     REFERENCE_POINT_INDEX to describe the nature of the point being
     referenced.
      
     See also the REFERENCE_POINT keyword, which locates the reference
     point in the physical units of the axes, rather than in index
     units (analogous to the FITS CRVALn keywords)."

      The ring observation id uniquely identifies a single experiment or

     identified within the Rings Node catalog.  It describes the smallest
     quantity of data that can be usefully cataloged or analyzed by itself.
     Note that a single observation may be associated with multiple data
     products (e.g. raw and calibrated versions of an image).  Note also
     that a single data product may be associated with multiple observations
     (e.g. a single WFPC2 image file containing four different images).  A
     ring observation id is constructed as follows:
     p/type/host/inst/time/... where p is a single-letter planet id (one of
     J, S, U, or N); type is IMG for images, OCC for occultation profile,
     etc.; host is the instrument host id, inst is the instrument id; time
     is the observation time as a date or instrument clock count; further

     values which conform to the above definition, such as time or spacecraft
     clock values.

     intentional driving is done. Each of those resets all later indices to 0

     hierarchical manner when they are incremented. Conceptually, a sixth value

     The telemetry source identifier element identifies the telemetry (TLM)

     TLM source may, however, be different over the lifecycle of a mission,

     0 (VC0) or virtual channel 1 (VC1) to a electrical ground support equipment
     (EGSE) computer 0 (EGSE_ID_0). The different routes can be defined with the
     telemetry source id element.
