Experiment Feedback

Onsala (A. Polatidis at Sat Sep 11 13:33:04 METDST 1999) Success
Observation went well. Unfortunately there was very strong RFI at the observing band. In addition there seems to be a TV repeater at 724-732 MHz. The continuum channels suffer most from the RFI.

Torun (K.Borkowski at Mon Sep 13 09:49:41 METDST 1999) Minor failures
Between 14:39 and 16:25 observations off source (one of antenna control computers hang up).

Effelsberg (A. Kraus at Mon Sep 13 10:46:39 METDST 1999) Minor failures
Problems with the tape drive led to the loss of the scans between UT2235 - UT2304 and UT2337 - UT0006. In addition, very strong RFI was present.

Westerbork (Tony Foley at Mon Sep 13 14:38:01 METDST 1999) Minor failures
Observation went OK, but EMI problems. EMI noticable from 15:00UT but came to saturation levels after about 20:15UT. I suspect that data from 20:15 to 03:00 is useless

Jodrell (Alastair Gunn at Wed Sep 15 12:14:25 METDST 1999) Minor failures
Second tape failed to start at requested time, picked up on 19:30 UT scan. Strong RFI. No other known problems.

Calibration (Jean\-Francois Desmurs at Sun Nov 7 15:23:12 MET 1999) Minor failures
