nothing to say

Westerbork (Tony Foley at Sun Feb 14 16:25:28 MET 1999) Success

no known failures, except total power about 3dB low. We used the tied-array setup.

Jodrell (Alastair Gunn at Sun Feb 14 18:15:59 MET 1999) Minor failures

Telescope encoder fault at 17:56 UT, source regained at 18:01 UT. Lost again between 19:26 and 19:30 UT. Lost communication with IF distributor sometime before 19:00 UT, attenuation lost, therefore data probably bad until approximately 20:15 UT.

HartRAO (Jonathan Quick at Mon Feb 15 12:38:47 MET 1999) Minor failures

Missed first source due to tape drive not in remote. Occasional problems with noise diode not firing. Otherwise OK

Torun (K.Borkowski at Mon Feb 15 13:13:52 MET 1999) Success

No known problems.

Noto (C.Trigilio at Tue Feb 16 18:21:55 MET 1999) Minor failures

Lost first 8 scans due to a software problem during re-configuration of field-system (from VLBA mode to MK3 mode). First valid data are from 09:56 (source 1958-179).

Shanghai (Huang Xinyong at Mon Feb 22 10:57:02 MET 1999) Success

The data are invalid from UT 17:28 to 17:42 and 20:06 to 20:12, because the elevation limitation of the antenna. It is fine.

Effelsberg (dgraham at Mon Feb 22 15:19:33 MET 1999) Success

Urumqi (Liu Xiang at Tue Feb 23 04:54:02 MET 1999) Minor failures

The experiment started at UT 08:02:50 because of the LO problem. The clock offset is 1.78us at begining, no P-cal.

Calibration (Jean\-Francois Desmurs at Wed Mar 3 11:18:49 MET 1999) Success
