[SOFA] Updates star catalog data for space motion. The *1 parameters are “before” values for TDB Julian Date jdtdb1. The *2 parameters are returned “after” values for TDB Julian Date jdtdb2. ra = right ascension (radians), dec = declination (radians), pmr = right ascension proper motion (rad/a), pmd = declination proper motion (rad/a), px = parallax (arcsec), rv = radial velocity (km/s receding). The input arguments must all have the same dimensions. The output variables get those same dimensions.
