UV_FITC

            This task allows fitting of simple models directly from the visibil-
        ities. The models are linear combinations of 2 radial distributions, as-
        sumed  to  be  centered  on the current phase tracking center. Use tasks
        UV_CENTER and UV_SHIFT if necessary before fitting.

        A more flexible and more general fitting procedure is available  in  the
        UVT  task.  This  version  is  more suitable for plotting a fit over re-
        binned visibilities.

        The type of the first radial distribution. Available types are
            NONE      No function to fit (for 2nd function usually)

            GAUSS     Gaussian sources
            DISK      Disk
            RING      Annulus
            EXPONENT  Exponential brightness
