[daip] SETFC

[Eric Greisen]

12282.  March 13, 2007              SETFC                Eric
        changed:
        (1) Formats to be clearer and handle VLBI better
        (2) Add message when user radius overrides the size
        (3) SETCEL error did not place return values for AIPS, leaving
            it to get garbage instead.
        (4) Changed BCHAN to 1 + 0.4*Nchan; ECHAN=BCHAN.  VLBI data
            frequently have channel 1 flagged.
        (5) When the user's radius limits the area, the CELLSIZE was
            set and then only the IMSIZE rounded to a power 2.
            Changed to adjust the CELLSIZE after the rounding some
            although not as drastically as when the two are set by
            maximum phase error.
        (6) Changed the round up levels substantially: if J > 1.05N
            recommend 2N where N is a power of 2 and J is the needed
            size w/o considering powers of 2.  Previously it did not
            round up until rather larger values of J.
        Moved nowhere.

Thanks for your help,

Eric
