MOSAIC_CLEAN

        MOSAIC_CLEAN

    This  task    contains    implementations    of    several    CLEAN-like
    deconvolution   algorithm  working on MOSAICs. The algorithm is selected
    through the METHOD$ keyword, which can be :
     SIMPLE    :  The straightforward direct method.
     CLARK     :  The Barry Clark major-minor cycle method.

    The input map and beam should have the  same  sizes,  except   for   the
    SIMPLE  method where different beam sizes are allowed, and must have the
    same grid spacing.  Sources are searched only in the  inner  quarter  of
    the  map,  but  their  sidelobes are removed in the full map.  A smaller
    search box can be specified if desired.

    The program can process all planes of a data cube at the same time,  but
    a   separate  list  of  component  will be produced for each plane.  The
    cleaning cannot be restarted.

    This task uses several input maps:
        .BEAM     A combination of the synthesized beams for all fields
                  in order (nx,ny,fields)
        .PRIMARY  A combination of the primary beams for all fields,
                  in order (fields,nx,ny)
        .LMV      The dirty mosaic, in order (nx,ny,nv)
    all produced by task MOSAIC from the individual fields.

    It produces a number of output maps
        .LMV-MOS  A cleaned, primary-beam corrected, image
        .LMV-RES  A residual image, without primary beam correction
        .CCT      A clean component table
