CALIBRATEVISIBILITY: Select PLOT, and flag first the
channels since their SNR is usually very low (if you observed with
the 3-way system; the 6-way system has only 16 channels). To do this, plot
VisSq vs channel, selecting all channels and the All-in-1 option. Then,
for calibration, look at the data from the calibrator stars (select them
using the information in the StarForm), then select CALIBRATE to
display the calibration widget. Make sure the star selection in the plot
widget is set to the stars to which you want the calibration be applied
before solving for a set of calibration coefficients. The calibration
will be applied to the data automatically. Save the calibration table
(entries) if you expect to restart
and want to redo some of the
calibrations. For more information on calibration, see section 18.5.
