16 smoothcal ---- Smooth calibration solution(s) derived from one or more sources 

17 

18  

19 A G- or T-type gain calibration can be smoothed. Amplitude and 

20 phase are currently smoothed with the same time. Calibration values 

21 will be smoothed over all fields.

27 tablein Input calibration table 

28 caltable Output calibration table (overwrite tablein if unspecified) 

29 field Field name list

39 A G- or T-type gain calibration can be smoothed. The amplitude and 

40 phase smoothing times are currently the same. Calibration values 

41 will be smoothed for only the specified fields. Smoothing is 

42 performed independently per field, per spw, and per antenna. 

43  

44 Keyword arguments: 

45 vis -- Name of input visibility file 

46 default: none; example: vis='ngc5921.ms' 

47 tablein -- Input calibration table (G or T) 

48 default: none; example: tablein='ngc5921.gcal' 

49 caltable -- Output calibration table (smoothed) 

50 default: '' (will overwrite tablein); 

51 example: caltable='ngc5921_smooth.gcal' 

52 field -- subset of fields to select and smooth 

53 default: '' means all; example: field='0319_415_1,3C286' 

54 smoothtype -- The smoothing filter to be used for both amp and phase 

55 default: 'median'; example: smoothtype='mean' 

56 Options: 'median','mean' 

57 smoothtime -- Smoothing filter time (sec) 

58 default: 300.0; example: smoothtime=60.
