Effelsberg (Uwe at Fri Jun 18 11:18:36 2021) Minor failures: HIGH

Some of the C-band observations show a strange behaviour of the Tsys vs. airmass. The receiver it self seems okay and no other obvious hardware reason could be found. It could be just RFI, but I wanted to mention this here just to have a note about it. Affected seem to be ES095B, EC077B, and ES099B. All other observations look normal.

Jodrell_Bank (Alastair Gunn at Fri Jul 02 13:57:56 2021) Minor failures: RFI

Calibration data for both Lovell and Mk2 telescopes at L-band this session are unusable due to severe RFI right across the band. The RXG files used in generating the antab files at L-band this session are from the last time the diode temperatures were successfully measured. These may not be correct so there is likely a scaling required on the derived Tsys for L-band experiments.
