    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  ob-
    servation (Obs_epoch, default 1950) and final result (New_epoch, default
    2000). The output catalog is 'Catalog_name'.SOU, and  has  the  standard
    format.

    /FLUX  create  a  copy  of the current catalog with only sources of flux
    larger than fmin

    /NAME ncname [iname]: reserve ncname characters for names  field.   With
    iname.gt.0, a standard name (Jhhmmmsddmmm) is created and put in inameth
    positions in the list of names.

    /INPUT FLUX filename : will take fluxes from filename, which has  itself
    the format of a catalog (both input catalog and filename are assumed al-
    phabetically sorted)

    /INPUT POSITION filename dpos : will take positions  from  filename,  if
    different  by more than dpos arc seconds. Filename has itself the format
    of a catalog (both input catalog and filename are assumed alphabetically
    sorted)

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