        NEW TASK: POLTS is a test program to examine the Rice bias
        in amplitudes, specifically for polarization but should also
        work for visibility amplitudes.  It begins by making a list
        of 1000000 random numbers using the usual AIPS random number
        generation scheme.  Then it does a loop over actual real
        and imaginary values and evaluates the amplitude over the
        1000000 random numbers with a different starting point and
        stride for real (Q) and imaginary (U).  It then calls the
        subroutine used by COMB, the subroutine used by POLCO, and
        a new subroutine to evaulate the Rice bias corrections.
        It writes a text file suitable for AIPS task PLOTR with 11
        numbers for each step in polarization.  The fitting
        capability of PLOTR was used to develop the new subroutine.
        The good news is that all of them work rather well with an
        error of about 0.004 sigma for COMB and the original routine
        in POLCO and a bit less (0.001 sigma) for the new routine.
        The bias (error) gets rather larger for S/N < 5.
        Moved nowhere.

16407.  April 14, 2026        POLCO, COMB                 Eric
        Changed the help file for COMB to mention POLCO and this
        new test.  Changed the HELP file and Fortran to add the
        new subroutine as an alternate choice (the default) in
        POLCO.
        Moved nowhere.

16408.  April 14, 2026            PATGN                    Eric
        Added FLUX as a noise parameter to be added to the pattern
        images.
        Moved nowhere.

16409.  April 14, 2026            PLOTR                    Eric
        Added adverb PIXRANGE to control the Y axis scale.  Changed
        APARM(3) and APARM(4) to be a range on the X axis to be
        used in fitting.  Previously, all data points were used in
        the polynomial fit even if only some of them were to be
        plotted.  Changed AU2A (PLGET) and AU8A (EXTLIST) for the
        change in PLOTR adverbs.
        Moved nowhere.
