VEGAS First Integration Tsys Problem
The problem
Jay's student noticed that Tsys was periodically very high in their data and so they reported the problem. From looking at their data, I can confirm the following:- The data are frequency switched observations taken in VEGAS observing mode 23
- The high Tsys values always fall in the first integration of each scan (both polarizations)
Resolution
- For now, recommended that they blank the first integration of each scan
