Example

 
        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
