      Description

      I share the concern that we're going to spend a lot of effort on handling illegal WCS headers, but this one's easy, and we already have a partial fix for the SDSS headers which use a string but no "J" prefix.

      Skymapper uses "J2000.0" not 2000.0 for its EQUINOX. Our code silently converts this to float using atof, and thus interprets it as 0.0 and deduces FK4 (which we don't support).
