SELF_NITER

    Variable length array specifying the number of Clean components retained for
    each  loop of the self-calibration process.  Default is 0, meaning all Clean
    components found by CLEAN.

    For simple structures and Phase calibration, 10 may be enough. For more com-
    plex ones, be sure to include enough Clean components in  the  model.   More
    components can be taken at each step, although the better knowledge of phase
    errors  often  allows  the source to be represented with a smaller number of
    components after self-calibration than before.  The default is a  reasonably
    good  compromise,  although  faster convergence may be obtained with smaller
    number of components.

    This variable length array can be resized using the LET /RESIZE command. For
    example
        LET SELF_NITER 10 0 0 /RESIZE
    will lead to 3 self-calibration loops (if SELF_TIMES  and  SELF_MINFLUX  are
    also  of size 3), the first one selecting only 10 components, the two others
    all components.
