MAP_COMPRESS Output

        [CLEAN\]MAP_COMPRESS WhichOne Nc [First TYPE] [Output]

    Output is a string indicating where the results will be placed.  It can be
        - Any SIC Image Variable that is not a built-in buffer in IMAGER
          The variable must exist and be of adequate size.
        - A file name. The command will write the result as a GILDAS data file
          with this name.
    The  distinction  between  SIC  Image Variable and Filenames is based on the
    presence of a dot (".") or semi-colon (":") that indicate  that  the  string
    refers to a filename.

    Output  is compulsory unless WhichOne referes to one of the allowed built-in
    buffer names (DIRTY, CLEAN or SKY) and forbidden if  WhichOne  is  *.   When
    Output  is  not  present,  the  result are written in place on the specified
    buffers.
