ROBUST

        [CLEAN\]UV_STAT ROBUST [Start [Step]]

    For ROBUST, beam sizes and noise level (in flux and brightness) will be com-
    puted for  9  different  MAP_ROBUST  weighting  parameters  (from  Start  to
    Start*Step^9).  Default  value  for  Step is sqrt(10), and default value for
    Start is derived to center the "robust" parameter values around 1.  UV  cell
    size  is  taken  from  variable MAP_UVCELL, and Taper is taken from variable
    UV_TAPER.
