[fitsbits] Plate coordinate tolerances

You did not say that it was a DSS image! The presence of EQUINOX indicates IAU1985/FK5 equatorial coordinates at equinox J2000.0. EPOCH here means the epoch of observation, i.e. DATE-OBS, as stated in the comment. I suggest you consult the literature or ask the DSS authors concerning the accuracy of the DSS plate solutions.
