Remarks

The astrometric catalogue data for a star; equator and equinox and units will depend on the catalogue. While this structure can be used as a generic container for catalogue data, all high-level NOVAS-C functions require J2000.0 catalogue data with FK5-type units (shown in square brackets below).
