Method Details

### __init__ (self, epoch, datum, name='') (Constructor) |
New RefFrame. Arguments: `epoch` - Epoch, a fractional calendar year (`scalar` or `str`). `datum` - Datum or ellipsoid (Datum, {Ellipsoid}, Ellipsoid2 or a_f2Tuple). `name` - Unique, non-empty name (`str`). Raises: `NameError` - A RefFrame with that `name` already exists. `TRFError` - Invalid `epoch`. `TypeError` - Invalid `datum`. Overrides: object.__init__

### __matmul__ (self, point) |
Convert an ellipsoidal `point` to this reframe and epoch. Overrides: named._Named.__matmul__ See Also: Method `toRefFrame`.

### toRefFrame (self, point, reframe2, **epoch2_epoch_name) |
Convert an ellipsoidal point from this reframe and from `epoch` to an other `reframe2` and `epoch2 or epoch`. Arguments: `point` - The point to convert (`Cartesian` or `LatLon`). `reframe2` - Reference frame to convert to (RefFrame). `epoch2_epoch_name` - Optional keyword arguments `epoch2=None`, `epoch=None` and `name=NN`. Returns: A copy of the `point`, converted or renamed. Raises: `TypeError` - Invalid `point`. Note: The `point`'s `reframe` and `epoch` are overridden by this reframe and `epoch` or this reframe's epoch. See Also: Ellipsoidal methods LatLon.toRefFrame and Cartesian.toRefFrame for more details.

### toStr (self, epoch=None, name='', **unused) |
Return this reference frame as a text string. Arguments: `epoch` - Override this reframe's epoch (`scalar` or `str`). `name` - Override name (`str`) or `None` to exclude the reframe's name. Returns: This RefFrame's attributes (`str`). Overrides: named._Named.toStr

### Xform (self, reframe2) |
Get the converter Xform from this reference frame to `reframe2`. Arguments: `reframe2` - Destination frame to convert to (RefFrame or `str`). Returns: The TRFXform instance or `None` if not available. Raises: `TypeError` - Invalid `reframe2`.

### Xforms (self, inverse=False) |
Return all Xforms converting from or to this reference frame. Arguments: `inverse` - If `True`, get all inverse, to Xforms (`bool`). Returns: An ADict of from `[refName2]=`TRFXforms) or if `inverse=True` of to `[refName1]=`TRFXforms).

Property Details

### datum Get this reference frame's datum (Datum). Get method: datum(self) - Get this reference frame's datum (Datum). Set method: _fset_error(inst, val) - Throws an `AttributeError`, always. Delete Method: _fdel(inst) - Zap the cached/memoized `property` value.

### ellipsoid Get this reference frame's ellipsoid (Ellipsoid or Ellipsoid2). Get method: ellipsoid(self) - Get this reference frame's ellipsoid (Ellipsoid or Ellipsoid2). Set method: _fset_error(inst, val) - Throws an `AttributeError`, always. Delete Method: _fdel(inst) - Zap the cached/memoized `property` value.

### epoch Get this reference frame's epoch (`Epoch`). Get method: epoch(self) - Get this reference frame's epoch (`Epoch`). Set method: _fset_error(inst, val) - Throws an `AttributeError`, always. Delete Method: _fdel(inst) - Zap the cached/memoized `property` value.
