CLEAN_FRES

###
CLEAN_FRES

        This is the minimal fraction of the peak flux in the dirty map that  the
        program  will  consider  as  significant.   Alternatively,  an  absolute
        threshold can be specified using CLEAN_ARES.  Once this level  has  been
        reached the program stops subtracting, and starts the restoration phase.
        This parameter is normalized to 1 (neither in % nor in db).   It  should
        usually  be of the order of magnitude of the inverse of the expected dy-
        namic range of the intensity.

        If 0, CLEAN_ARES will be used instead. If all of CLEAN_NITER, CLEAN_ARES
        and CLEAN_FRES are 0, an absolute residual equal to the noise level will
        be used for CLEAN_ARES.

        Short form is FRES.
