22 --------- parameter descriptions --------------------------------------------- 

23 

24 fitsfile Name of input UV FITS file 

25 vis Name of output visibility file (MS) 

26 antnamescheme VLA/EVLA/CARMA only; \'new\' or \'old\'; \'VA04\' or \'04\' for VLA ant 4

28 --------- examples -----------------------------------------------------------

31 Convert a UVFITS file to a CASA visibility data set: 

32  

33 Keyword arguments: 

34 fitsfile -- Name of input UV FITS file 

35 default = none; example='3C273XC1.fits' 

36 vis -- Name of output visibility file (MS) 

37 default = none; example: vis='3C273XC1.ms' 

38 antnamescheme -- Naming scheme for VLA/JVLA/CARMA antennas 

39 default = old; 

40 old: Antenna name is a number, '04' 

41 This option exists for backwards compatibility 

42 but can lead to ambiguous results when antenna 

43 indices are used for data selection. 

44 new: Antenna name is not a number, e.g., 'VA04' or 'EA04' 

45 With this scheme, data selection via 

46 antenna names and indices is non-ambiguous. 

47  

48 Note: Don't forget to flag autocorrections using 

49 taskname flagdata, autocorr = true
