Gain plots for XX and YY correllations

[Ermiasabebe]

The calibration process goes well except warning during the plot routine (unable to get the plots). The reason, as I suspect, is the MS data has no XY and YX correlations. The error in the log is:

Can we fix the code so as to get the Gain plots in the process ?
