Experiment Feedback

Westerbork (Tony Foley at Fri Feb 21 09:45:35 EST 1997) Minor failures

Lost first scan (0800-0803) as telescopes were not on source. Experiment ended early at Westerbork as the sources were outside our hour angle range from ~1400UT.

Medicina (D.Dallacasa at Fri Feb 21 14:48:49 EST 1997) Success

Source sets 45 min before end of the schedule

Onsala (Antonis Polatidis at Sun Feb 23 09:00:54 EST 1997) Minor failures

Due to high winds we had to stow the antenna at UT 1105.

Effelsberg (dgraham at Mon Feb 24 03:28:04 EST 1997) Success

OK. This was not supposed to be a double speed experiment.

Jodrell (Alastair Gunn at Wed Mar 5 08:36:37 EST 1997) Minor failures

No major problems. Missed scan before 16:41 due to azimuth un-wrapping. Tapes EVN0086,CA90 IRAM0084,078F and JODV0062,C8B9 sent to Socorro via Fedex on 24/02/97.

Cambridge (Alastair Gunn at Wed Mar 5 08:44:00 EST 1997) Minor failures

No major problems. Formatter clock discovered to be behind GPS by 2 seconds and fixed for 09:40 scan. Problem was not present one hour before this. Tapes EVN00118,C6FC MPIR1184,B747 and EVN00035,5ACD sent to Socorro via Fedex on 24/02/97.

Calibration (Fredrik T Rantakyro at Thu May 8 11:34:49 METDST 1997) Success

The ANTAB file for the experiment has been placed on VLBEER in the Feb97 directory with the name gp15a.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.
