NAME:
  objcheck
 PURPOSE:
  Validate and summarize object positions and astrometry
 DESCRIPTION:
  Reads astrometry and obj files from the current directory looking for
    irregularites.  Recommendations are provided that suggest running astrom
    or looker on specific frames.  These recommendations always point to
    problem areas but sometimes the fix is something that takes care of a
    problem that astrom or looker had with that frame, rather than something
    that can be fixed by just running the programs.
 CATEGORY:
  Astrometry

 INPUTS:

 OPTIONAL INPUT PARAMETERS:

 KEYWORD INPUT PARAMETERS:
  JUSTLOOK   - Flag, if set turns off some printouts.  This is not that useful
                 and may well disappear in later versions.

  KILLSINGLE - Flag, as the obj files are read, scan for objects marked 'y' that
                 have zero or one valid positions.  For any found, mark them
                 'n' and add "crud" to the id string.

 OUTPUTS:
  The file, check.lst, is written with the same information that is sent
    to the screen to facilitate cleaning up any problems found.
