Here's an example of what can be done. Copy and paste this into a file on the pfcs machine, then '​source'​ it.

 +This will make a 2 x 2 plot showing pointing offsets, points on the sky observed, Tsys vs El (and a fit to Tsys vs sec(z)) and Elevation offset vs elevation. Clicking in the plot window will dismiss the plot.
