VIEW

        [DISPLAY\]VIEW Argument [FirstPlane  [LastPlane]]  [/NOPAUSE]  [/OVERLAY
    [...]] [/DIRECTORY TreeName]


    where (in the most general case, see details for specific Keywords)
        is  the  the name of an internal buffer to be plotted (BEAM, CCT, CLEAN,
    DIRTY, FIELDS, MASK, etc.. ), or any Sic Image variable, or a file name.

        [DISPLAY\]VIEW ?

    will list the names of recognized keywords. If Variable is not  one  of  the
    recognized keywords, but an existing Image variable, this image will be dis-
    played.

    FirstPlane and LastPlane
        are  optional  arguments to restrict the range of channels to be plotted
    (default: planes between variables FIRST and LAST). If  only  FirstPlane  is
    specified, SHOW only that plane.

    VIEW is also controlled by a set of variables, available in the View% global
    structure. VIEW shows 4 (or 6) panels, representing the Integrated area, the
    current  channel,  and  the Integrated spectrum and the current spectrul (in
    possibly 2 different scales). An interactive control of the View is possible
    using the cursor, unless the /NOPAUSE option is given.

    The spectral panels can display line identifications based  on  the  current
    CATALOG. If a variable REDSHIFT exists, the frequency scale is corrected for
    the source Redshift, so that line identification remains possible.
