            [CLEAN\]UV_RESTORE /SPEED Mode [/COPY]

        Create a Clean image from the current UV data set and the  Clean  Compo-
        nent  list,  using the specified Mode to remove the Clean Components be-
        fore imaging the residuals.

        The argument Mode may be one of the following keyword:
        AUTO    Automatically select the "fastest" method, according to the
              current number of Visibilities and Clean components.
        FFT     Subtract Clean Components by FFT and interpolation onto
              individual visibilities.
        PRECIS  Subtract the Clean Components by simple Sin/Cos phase terms
              for each visibility
        The PRECIS mode is faster for a small number of visibilities  and  Clean
        components, while the FFT mode is faster for large ones.

        Instead of the above keywords, Mode may also be a number which specifies
        when the AUTO mode should switch from PRECIS mode to FFT mode.   The de-
        fault  number  to  control the AUTO mode is 200 Millions (product of the
        number of visibilities and average number of Clean components per  chan-
        nel).  This  value  is "sticky": if changed by /SPEED, the new values is
        retained until next change.
