      Description

      Currently, coordinates (coord_ra and coord_dec) in source catalogs (FITS files) are in radians with not units or documentation in the file itself. The astronomical convention is to use degrees for coordinates (or hours for RA, but that is falling out of favor). I think that we should follow this standard and make it a LSST convention to always use degrees for coordinates in "external" files that people might load from other packages (the internal storage of coordinates is a separate issue). Also, we should put the units in the file for documentation purposes and so it will be easier to interpret the results on ingest.

      This might need a RFC but since I'm not sure if there's anyone available to work on this right now I'm just going to file a ticket.
