Get the star parameters in a different catalog.
Only the RA and Dec. are computed.
| modelId | Model id. | |
| time | Time of the input star. | |
| newCatalog | New catalogue where the new parameters are computed. |
References dec, muDec, muRa, parallax, ra, radVel, EECFI::Time::ref, StarData(), EECFI::CfiClass::throwWarn, and EECFI::Time::time.
Get cartesian coordinates in the requested CS.
Only the position and velocity vector are computed (not the accelearation).
| modelId | Model Id. | |
| deriv | flag to indicate if derivatives have to be computed (XLCFI_NO_DER, XLCFI_DER_1ST). |

| ) | const |
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).
