Two patches have been issued:

12570.  March 4, 2008       model division               Eric
        The correct weights after model division are multiplied by
        amplitude squared, not amplitude.  The gridded modeling was
        corrected years ago, but the DFT was not until today.
        Fixed QPTDIV, QGADIV, and QSPDIV.
        Moved to 31DEC07 patch March 5.

12572.  March 5, 2008             FILLM                 Eric
        FILLM has been scaling and weighting cross-hand data
        incorrectly in those cases in which the antenna order in the
        on-line system is reversed from the antenna order implied by
        the numbers painted on the sides of the telescope.   The
        reversal took place before the scaling and weighting and it
        must take place after since we cannot change the antenna
        numbers themselves.  Note that this affects ModComp-era data
        when converted to correlation coefficients and post-Modcomp
        data when converted to visibilities.  It affects weights of
        Modcomp-era data when not converted to correlation
        coefficients.  The affects on solar data cross-hands are
        more extensive since they are converted to correlation
        coefficients.
        Moved to 31DEC07 patch this date.

These may be installed in the old way if you compile 31DEC07 locally
via http://www.aipc.nrao.edu/31DEC07/patches.html.  The MNJ on 31DEC07
will also pick them up along with a file needed by VLANT and two
previous patches (FITLD and REBYTE).
