No known problems
Medicina (Fiocchi Franco at Sun Nov 17 08:06:05 2002) Minor failures : TSYS
Our tsys values are not defined because the calibration system is not able for this observation frequency.
Urumqi (Sun Zhengwen at Sun Nov 17 08:55:59 2002) Minor failures : HIGH PARI
Due to Weather,there's a little snow on the antenna surface,so the Tsys hight.
Onsala (Michael Lindqvist at Sun Nov 17 09:09:16 2002) Minor failures : RECO
1. GPS-formatter difference changed from about 6 to 56.2 us.
2. Problem with tapedrive: pass command gave pass/1,101 instead of

No known problems.
Cambridge (Alastair Gunn at Mon Nov 18 15:04:29 2002) Success :
Due to MERLIN link restrictions, signal only appears in
BBCs 3 and 4. No known problems. No valid Tsys measurements.
Arecibo (Tapasi Ghosh at Wed Nov 20 14:39:06 2002) Minor failures : LATE RECO
1. One of the write drivers was removed from the recorder to investigate the "Track 18 problem". As it wasn't possible to
place it back before the run, we went ahead and ran the experiment in the usual way without the write-driver # 2. Hence, headstack 2 didn't write any data on tape (please accept our apologies. Meanwhile, Track #18 trouble has been located to a loose capacitor within that
module and it is beleived to be fixed now).
2. As the one of the local control computers needed rebooting, the
first 4 mins of the run couldn't be recorded.
