STORE CORRECTION

            CLIC\STORE CORRECTION [GOOD|BAD|AUTO|SELF [tmin]]  [/RECEIVER  irec]
        [/ANTENNA a1 ...] [/FRACTION fraction]

        Store  in the header of each scan (of the current index) the information
        whether the atmospheric phase correction is or not declared  valid,  and
        should  be  actually  applied when SET PHASE ATM is selected. This is an
        antenna-based flag.

          - GOOD: the atmospheric phase correction is to be used.

          - BAD: the atmospheric phase correction is not to be used.

          - AUTO [tmin]: that information is determined on the phase calibrators
            (type  PHASE),  by  comparing  the scan-averaged amplitudes with and
            without the correction. This information is then propagated  to  the
            neighbouring source observations (type OBJECT), in a +- tmin minutes
            time window.  `tmin' defaults to 15 minutes.

          - SELF: that information is determined on  the  source,  whatever  its
            type may be, by comparing its amplitude with and without the correc-
            tion. This will produce random result if the source has no continuum
            emission.

          -  STORE  CORRECTION  /RECEIVER  irec: the validity  of the correction
            from Receiver 'irec' is used (useful to transfer the correction  va-
            lidity from one frequency to the other).

        With  option /ANTENNA a1 a2 ..., only the specified antennas are consid-
        ered. The correction validity for other antennas is not modified.

        With option /FRACTION fraction, fraction of amplitude will  replace  the
        noise in estimating if uncorrected is better than corrected.
