Hartebeesthoek (Jonathan Quick at Tue Nov 09 06:27:35 2021) Success:

No known problems.

Yebes (Ruben Fernández at Tue Nov 09 08:38:50 2021) Success:

Not using continuous calibration due to failure in noise diode. Changed to GAP calibration with hot load at startup.

Zelenchukskaya (Ptitcin A. at Tue Nov 09 09:25:15 2021) Minor failures:RECE ANT

Scans from no0022 to no0028 due to intensive geo session Scans from no0001 to no0006 fialed - LO failure Scans from no0082 to 0084 missed due to antenna problems.

Badary (Semenova, Zadrutsky, Slepkova at Tue Nov 09 09:25:59 2021) Success:

Skipped scans No0022-No0029 due to intensive geo session

Svetloe (Baykova at Tue Nov 09 09:26:14 2021) Success:

Onsala (Jun Yang at Tue Nov 09 13:17:20 2021) Success:

No known problems. The Chopper Wheel calibration was used. So, the Tsys data were opacity corrected

Medicina (Giuseppe Maccaferri at Tue Nov 09 13:37:01 2021) Success:

Noto (Salvo Buttaccio at Wed Nov 10 11:32:40 2021) Success:

No known problems

Yebes (Daniel Valero at Thu Nov 11 10:38:30 2021) Success: PCAL

No phasecal available for K band

Urumqi (Hua Zhang at Thu Nov 11 13:16:07 2021) Success:

Urumqi (Hua Zhang at Thu Nov 11 13:20:32 2021) Success:

Unable to generate antab file.

Jodrell_Bank (Alastair Gunn at Mon Nov 15 10:24:01 2021) Minor failures:RECE

Fixed Rx was fixed just as the experiment started so first few scans may be not on source. No other known problems.

Effelsberg (Uwe at Mon Nov 15 10:56:17 2021) Minor failures: PCAL

First 1.5h were observed with phase-cal ON, but the phase-cal unit seems to be broken. It emits too much power into the IF and causes am increase of the noise. Phase-cal was turned OFF at 17:34 UT and data looked better.
