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).
