Smoothcal
From CASA Guides
Help on smoothcal task:
Smooth calibration solution(s) derived from one or more sources: A G- or T-type gain calibration can be smoothed. The amplitude and phase smoothing times are currently the same. Calibration values will be smoothed over all fields designed. Keyword arguments: vis -- Name of input visibility file default: none; example: vis='ngc5921.ms' tablein -- Input calibration table (G or T) default: none; example: tablein='ngc5921.gcal' caltable -- Output calibration table (smoothed) default: none; example: caltable='ngc5921_smooth.gcal' field -- subset of fields to select and smooth default: '' means all; example: field='0319_415_1,3C286' smoothtype -- The smoothing filter to be used for both amp and phase default: 'median'; example: smoothtype='mean' Options: 'median','mean' smoothtime -- Smoothing filter time (sec) default: 300.0; example: smoothtime=60.
