Detailed Description

FK4 RA, Dec; date is Besselian years, and is both the date of observation and the date of equinox

Cannot be current because it has a date of equinox

Warning: the FK4 system has significant fictitious proper motion. Coords will be treated as fixed (the fictitious proper motion removed) if you specify proper motion AND radial velocity as zero. If any component of propoer motion or radial velocity is nonzero, then all components are treated as correct. Thus it is usually safest not to specify radial velocity for FK4 targets.
