Detailed Description

A partial representation of a full LSST Object containing only id, position, proper motions, and per-filter variability probabilities.

This is sufficient for performing spatial crosss matches. None of these fields may ever be NULL.

double lsst::ap::Object::getDec ( ) const

inline

Returns: Declination (degrees)

Definition at line 72 of file Object.h.

                           {
         return _decl;
     }

double lsst::ap::Object::getEpoch ( ) const

inline

Returns the epoch of the position (getRa(), getDec()). New objects created from difference sources are created with zero proper motion so returning an incorrect epoch for those positions has no effect on association. Therefore, this method can always returns J2000 in MJD(TAI) and there is no need to store epochs in chunk files: object positions measured by deep detection are assumed to be in equatorial J2000.0 coordinates at epoch = J2000.
