Experiment Feedback

Effelsberg (dgraham at Fri Feb 21 04:10:41 EST 1997) Minor failures
OK

Westerbork (Tony Foley at Fri Feb 21 08:44:50 EST 1997) Success
Looks OK

Medicina (D. Dallacasa at Fri Feb 21 14:41:08 EST 1997) Success
Occasionally few seconds lost due to mispointing due to comunication problems with the ACU

Onsala (Antonis Polatidis at Sun Feb 23 08:51:27 EST 1997) Minor failures
Due to high winds had to stow the antenna from UT 0632 onwards. Only the last two scans were lost. Otherwise no known problems

Shanghai (Huang Xinyong at Wed Mar 5 04:56:26 EST 1997) Success
Clock offset = 0.08 msec. No problems, weather fine.

Jodrell (Alastair Gunn at Wed Mar 5 07:33:00 EST 1997) Minor failures
Telescope was parked due to high winds at 22:18 UT. No other known problems. Tapes NGS00382,028F and USNO0222,6A0D sent to Bonn via Woodcroft on 24/02/97.

Cambridge (Alastair Gunn at Wed Mar 5 07:36:02 EST 1997) Minor failures
Telescope parked between 20:35 and 21:51 due to high winds and then parked again from 23:50 for rest of experiment. No other known problems. Tapes JODR0019,5370 and HSS00068,E804 sent to Bonn via Woodcroft on 24/02/97.

Calibration (Fredrik T Rantakyro at Thu May 8 11:33:44 METDST 1997) Success
The ANTAB file for the experiment has been placed on VLBEER in the Feb97 directory with the name em21b.antab. This file contains the preliminary calibration results and may be updated when I receive updated information from the telescopes and the results from the datareduction of the calibration experiments.

MPIfR (Walter Alef at Wed Jan 7 12:00:44 MET 1998) Minor failures
Crimea and Noto did not observe. No fringes with Cambridge and Urumqi. Time lost due to high winds. Typically nearly half the stations lost. Standard recording problems.
