TAPER

        [CLEAN\]UV_STAT TAPER [Start [Step]]

    For  TAPER, beam sizes and noise level (in flux and brightness) will be com-
    puted for 9 different tapers (from Start to  Start*Step^9).   Default  value
    for  Step  is  sqrt(2),  Default value for Start is 50 m. Weighting mode, UV
    cell size and "robust" parameter are  taken  from  variable  MAP_UVCELL  and
    MAP_ROBUST (i.e. one can combine Robust weighting and Tapering).
