Variables:

    The  SELFCAL  behaviour  can  be  adjusted  through  control variables named
    SELF_... (see EXA SELF_ for a list), in addition to the control variables of
    UV_MAP (MAP_...) and CLEAN (CLEAN_...)

    The most important variable is SELF_TIMES, a  variable  length  array  which
    controls the integration time at each loop. SELF_NITER and SELF_MINFLUX also
    control  the  number  of  Clean components and minimum flux retained in each
    loop. The size of these arrays define the number of loops.

    See HELP SELFCAL SELF_LOOP to find out how to control the number of loops.
