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 OYSTER and want to redo some of the calibrations.
For more information on calibration, see section 7.6.
