        Convert a UVFITS file to a CASA visibility data set:

        Keyword arguments:
        fitsfile -- Name of input UV FITS file
                default = none; example='3C273XC1.fits'
        vis -- Name of output visibility file (MS)
                default = none; example: vis='3C273XC1.ms'
        antnamescheme -- Naming scheme for VLA/JVLA/CARMA antennas
                default = old;
                  old: Antenna name is a number, '04'
                       This option exists for backwards compatibility
                       but can lead to ambiguous results when antenna
                       indices are used for data selection.
                  new: Antenna name is not a number, e.g., 'VA04' or 'EA04'
                       With this scheme, data selection via
                       antenna names and indices is non-ambiguous.
        async --  Run asynchronously
               default = false; do not run asychronously

        Note: Don't forget to flag autocorrections using
           taskname flagdata, autocorr = true
