Experiment Feedback

Effelsberg (dgraham at Thu Feb 20 02:56:00 EST 1997) Minor failures
stop for wind 2130 to 0015

Medicina (Operator \(Mariotti\) at Thu Feb 20 04:48:20 EST 1997) Success
It seem everything OK

Westerbork (Tony Foley at Thu Feb 20 05:27:04 EST 1997) Success
No known problems

Onsala (Antonis Polatidis at Sun Feb 23 08:41:44 EST 1997) Minor failures
Due to high winds (>14m/s) we stowed the antenna between UT 2310 and Ut 0558 and then from 0635 to the end of the schedule. No known problems for the recorded data.

Shanghai (Huang Xinyong at Wed Mar 5 04:52:02 EST 1997) Minor failures
Clock offset = 0.06 msec. Tape vacuum failed four times in first scan(21:00:00-21:13:00). Weather fine.

Jodrell (Alastair Gunn at Wed Mar 5 07:29:01 EST 1997) Minor failures
Telescope was parked due to high winds until 03:40 UT. No other known problems. Tapes IAA00326,1CD3 and MPIR1135,D71B sent to Bonn via Woodcroft on 25/02/97.

Cambridge (Alastair Gunn at Wed Mar 5 07:43:15 EST 1997) Minor failures
Field system crashes occurred at 03:48, 06:30 and 07:52. Telescope was parked due to high winds until about 04:00 UT. No other known problems. Tapes IAA00141,40FB and EVN00023,B2AC sent to Bonn via Woodcroft on 24/02/97.

Calibration (Fredrik T Rantakyro at Thu May 8 11:33:35 METDST 1997) Success
The ANTAB file for the experiment has been placed on VLBEER in the Feb97 directory with the name em21a.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 11:57:26 MET 1998) Minor failures
Crimea and Noto did not observe. No fringes with Urumqi. Several antennas lost time due to high winds. More than half of telescopes lost on average. Problems with recording quality.
