CONVERT

        [ASTRO\]CONVERT  [Catalog_Name]  [/ALTERNATE]  [/J2000  [Obs_epoch]]
    [/PRECESS [New_epoch]] [/GALACTIC]

    Change catalog format or epoch.

    Without any option (or with option  /ALTERNATE)  and  without  argument,
    this command creates an OBSINP-compatible copy of the 'name'.SOU catalog
    (or Alternate  catalog  if  /ALTERNATE  is  specified)  under  the  name
    'name'.CAT.

    With the /J2000 and/or /PRECESS option, the  command  will  precess  the
    current  SOU  catalog  to  J2000  system, using the specified epochs for
    observation (Obs_epoch,  default  1950)  and  final  result  (New_epoch,
    default  2000).  The  output catalog  is 'Catalog_name'.SOU, and has the
    standard format.

    /ALTERNATE option : do the same operation with the Alternate catalog.
