SUPPORT /MASK

###
SUPPORT /MASK

            [CLEAN\]SUPPORT /MASK    or  [ADVANCED\]MASK USE

        Use  the  mask  defined by READ MASK or by the MASK command as the clean
        support. This does not suppress the current polygon: it  can  be  re-in-
        stated by a simple SUPPORT command with no argument.

        The  Mask  can be a 3-D array: CLEAN will find out which mask plane must
        be used for each spectral channel.

        Caution: [CLEAN\]READ MASK and [ADVANCED\]MASK command do not perform an
        implicit  SUPPORT /MASK command. Only the ADVANCED\MASK USE command does
        it explicitely.
