0.1.122 smoothcal
Requires:
Synopsis
Smooth calibration solution(s) derived from one or more sources:
Description
A G- or T-type gain calibration can be smoothed. Amplitude and phase are
currently smoothed with the same time. Calibration values will be smoothed
over all fields.

Example
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 for only the specified fields. Smoothing is
performed independently per field, per spw, and per antenna.
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: ’’ (will overwrite tablein);
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.
