UV_REWEIGHT DO

            [CLEAN\]UV_REWEIGHT DO [Tolerance [Printout]] [/RANGE Min Max Type]
          [/FLAG Threshold]

        Derive the scale factor from the noise statistics over the channels, and
        use it to rescale the weights.  The noise statistic is derived from  the
        real  and imaginary parts separately, taking mean value,  or the minimum
        of the twos when the mean/min ratio is smaller than specified  Tolerance
        (default is 1.2).

        The  /FLAG  option  indicates whether data with highly deviating weights
        should  be  flagged.  UV_REWEIGHT  DO  combines  the  two   actions   of
        UV_REWEIGHT ESTIMATE (or TIME) and UV_REWEIGHT APPLY, but with a control
        over these outliers (that are not identified by APPLY).

        Mode DO uses the ESTIMATE method if the number of channels is > 16,  the
        TIME method if not.

        Printout  is  a number indicating to print some correction factors every
        Printout visibility (no print if 0, the default)  (for  ESTIMATE  method
        only).
