Member Function Documentation

StarData EECFI.StarData::changeCatalog ( ModelId  modelId,
Time  time,
long  newCatalog 
) throws CfiError

Get the star parameters in a different catalog.

Only the RA and Dec. are computed.

Parameters:
modelId Model id.
time Time of the input star.
newCatalog New catalogue where the new parameters are computed.
Returns:
Star parameters in new catalog.
Coord EECFI.StarData::getCart ( ModelId  modelId,
long  deriv 
) throws CfiError

Get cartesian coordinates in the requested CS.

Only the position and velocity vector are computed (not the accelearation).

Parameters:
modelId Model Id.
deriv flag to indicate if derivatives have to be computed (XLCFI_NO_DER, XLCFI_DER_1ST).
StarRaDec EECFI.StarData::getStar ( ModelId  modelId,
Time  time 
) throws CfiError

Get star Ra and Dec in ToD for a given time.

The object StarData values are used as a reference and it it should be given in FK5 catalog (BM2000 CS).

Parameters:
modelId Model id.
time Time for which the values are requested.
