    Change catalog format or equinox.

    With the /J2000 and/or /PRECESS option, the  command  will  precess  the
    current SOU catalog to J2000 system, using the specified equinox for ob-
    servation (Obs_equinox, default 1950) and final result (New_equinox, de-
    fault 2000). The output catalog is 'Catalog_name'.SOU, and has the stan-
    dard 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.
