Experiment Feedback

Medicina (A. Cattani at Mon Nov 22 21:37:20 MET 1999) Minor failures

Until 10:30 UT the Tsys may be not calibrated

Shanghai (Huang Xinyong at Mon Nov 22 23:11:08 MET 1999) Success

Effelsberg (A. Kraus at Tue Nov 23 09:08:45 MET 1999) Minor failures

Due to snowfall the observation could not start earlier than UT1220. After that, everything looked fine.

Jodrell (Alastair Gunn at Tue Nov 23 10:55:30 MET 1999) Success

No known problems.

Torun (K.Borkowski at Tue Nov 23 11:28:05 MET 1999) Minor failures

Unfortunately serious (not minor) failures happened. First, due to a neglect of an observer, a recorded tape (of SAH6A) was used until 7:06. Then, at 17:25, a long (half an hour) power failure caused a few hardware damages which could not be repaired before the end of this experiment.

Onsala (A. Polatidis at Tue Nov 23 14:29:10 MET 1999) Success

Lost the last two scans (since 2010 UT) due to the telescpe unwrapping. Otherwise no problems

Westerbork (Tony Foley at Tue Nov 23 14:31:35 MET 1999) Minor failures

Several scans were out of hour angle range. After 15:16 these were replaced by local calibration sources. Mostly observed with 11 telescopes

Noto (C.Trigilio at Thu Nov 25 10:59:51 MET 1999) Minor failures

Strong wind may affect the pointing.

Calibration (Jean\-Francois Desmurs at Wed Dec 15 13:16:08 MET 1999) Success
