Note on RAh:
  Where bytes 1-54 are blank, bytes 55-127 belong to the previous record.
Note on DEm, DEm2000:
  DEd applies to both epochs of DEm. DEm values greater than 60 arcminutes
        result. These do not indicate errors in the data.
Note on rem:
  *     = Pair has been removed from the program
Note on mag1, mag2:
  blank = Null
  99.9  = Variable
Note on note:
  N     = Northern Declination
