CLEAN_NITER

    This  is  the  maximum  number of components the program will accept to sub-
    tract.  Once it has been reached, the program starts the restoration phase.

    If 0, the program will guess a number, based on the image size  and  maximum
    signal-to-noise  ratio,  and  specified  residual  level  CLEAN_ARES  and/or
    CLEAN_FRES.

    Short form is NITER.

    This may be overseded by the /NITER option which imposes a limit  per  plane
    through an array of values.
