Shanghai (Xinyong Huang at Fri May 23 00:52:20 2003) Minor failures : RFI

Seshan station stop the schedule at UT: 142_20:18:04, because of the sources out of our antenna's limit.

Medicina (A.Maccaferri at Fri May 23 01:14:28 2003) Minor failures : RECO FS

After tape change, recorder did not start, some command for markV, avoid tape to restart after label command. Lost about 20 minutes afetr tape change and about the same at the end of first pass.

Medicina (A.Maccaferri at Fri May 23 01:14:50 2003) Minor failures : RECO FS

After tape change, recorder did not start, some command for markV, avoid tape to restart after label command. Lost about 20 minutes afetr tape change and about the same at the end of first pass.

Urumqi (yangwj at Fri May 23 02:21:26 2003) Success :

from the UT 23:45,the source is outside telescope limits.

Torun (K.Borkowski at Fri May 23 04:46:13 2003) Success :

Due to long passes in Az 3 consecutive scans were affected: lost at 20:38, and about 3 min. late on source at 20:21 and 20:40. No other known problems.

Onsala (Michael Lindqvist at Fri May 23 09:18:37 2003) Success :

No known problems.

Effelsberg (A. Kraus at Sat May 24 12:06:26 2003) Minor failures : FS

Due to problems with our VLBA-FS, the last 45 minutes were lost

Noto (P. Cassaro at Tue May 27 12:04:03 2003) Success :

Noto (P. Cassaro at Tue May 27 12:10:30 2003) Success :

Jodrell_Bank (Alastair Gunn at Tue May 27 22:05:40 2003) Success :

Cambridge (Alastair Gunn at Tue May 27 22:06:29 2003) Success :

Reduced signal level in BBCs 1,2,7,8 due to MERLIN link restrictions.

Urumqi (Liu Xiang at Tue Jun 3 12:40:15 2003) Minor failures : TSYS FS

Comment: the lowest Tsys of BBCs in logfile (like 23K at LCP, 12K at RCP) should corresponds to 22K at LCP and 22K at RCP as we measured with radiometer; the FS has some problem with Tsys measure. so you could use a correction factor from above in ANTAB.

Westerbork (foley at Mon Jul 7 15:06:17 2003) Minor failures : PHAS

RTB unreliable. Used 13 telescopes in the array
