X-crystal spectrometer diagnostic

Notation of array of structure indices: itime indicates a time index; i1, i2, i3, ... indicate other indices with their depth in the IDS. This notation clarifies the path of a given node, but should not be used to compare indices of different nodes (they may have different meanings).

Lifecycle status: alpha since version 3.26.0

By convention, only the upper error node should be filled in case of symmetrical error bars. The upper and lower errors are absolute and defined positive, and represent one standard deviation of the data. The effective values of the data (within one standard deviation) will be within the interval [data-data_error_lower, data+data_error_upper]. Thus whatever the sign of data, data_error_lower relates to the lower bound and data_error_upper to the upper bound of the error bar interval.

ids_properties/comment Any comment describing the content of this IDS {constant} STR_0D
ids_properties/homogeneous_time This node must be filled (with 0, 1, or 2) for the IDS to be valid. If 1, the time of this IDS is homogeneous, i.e. the time values for this IDS are stored in the time node just below the root of this IDS. If 0, the time values are stored in the various time fields at lower levels in the tree. In the case only constant or static nodes are filled within the IDS, homogeneous_time must be set to 2 {constant} INT_0D

In case the node is the result of of a calculation / data processing, the source is an input to the process described in the "code" structure at the root of the IDS. The source can be an IDS (identified by a URI or a persitent identifier, see syntax in the link below) or non-IDS data imported directly from an non-IMAS database (identified by the command used to import the source, or the persistent identifier of the data source). Often data are obtained by a chain of processes, however only the last process input are recorded here. The full chain of provenance has then to be reconstructed recursively from the provenance information contained in the data sources. Click here for further documentation. {constant} STR_1D 1- 1...N
