Effelsberg (Uwe at Wed Feb 26 14:50:15 2020) Minor failures: HIGH

When switching the source in the middle of the observations the DBBC lost somehow the calibration on IFC. All LCP data shows an enormous increase in Tsys and huge spikes: e.g. http://old.evlbi.org/tog/ftp_fringes/N20C1/scan08/st04_lcp-st04_lcp-ch0-lsb-0-2_large.png Reason not understood yet.
