[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.
