NAME:
  ast2ted
 PURPOSE:
  Convert astrometry file to a Ted Bowell format astrometry file.
 DESCRIPTION:

 CATEGORY:
  Astrometry
 CALLING SEQUENCE:
  ast2ted,file,outfile,slowfile
 INPUTS:
  file     - Final astrometry file to read and summarize.
  outfile  - Name of file to write results to.
  slowfile - Name of file to write slow moving (or DES) objects to
                 (default=don't save slow objects to a separate file)

 OPTIONAL INPUT PARAMETERS:

 KEYWORD INPUT PARAMETERS:
  DESOBJ   - optional string array of names of DES interesting objects.
              if provided, this controls the objects that are written to
              slowfile.  The slow objects are not written to outfile.

 OUTPUTS:

 MODIFICATION HISTORY:
  2000/02/15, Written by Marc W. Buie, Lowell Observatory
  2001/04/18, MWB, added slowfile output option
  2002/09/09, MWB, added support for string obscode values
  2004/07/24, MWB, added DESOBJ keyword
  2005/05/25, MWB, changed output to ted files when handling DES objects
                      Slow moving/KBO objects are no longer saved to the
                      main output file AND to the slowfile.  Now objects
                      are saved in only one file.  If slowfile name is not
                      provided then DESOBJ is ignored and all objects are
                      saved to outfile.
  2005/10/12, MWB, fixed bug that prevented saving slow moving objects to a
                     separate file if the mysql-based list was empty
