Experiment Feedback

Onsala (Michael Lindqvist at Thu May 31 13:17:21 2007) Success :

No known problems.

Westerbork (Tony Foley at Thu May 31 13:45:20 2007) Minor failures :

Wb used in phased array mode. One telescope in the array (RT0) was not operating correctly, so there may be a slight reduction in sensitivity Otherwise OK.

Effelsberg (A. Polatidis at Thu May 31 13:56:07 2007) Minor failures :

There were no data on VC05. The video converter was exchanged for another one but the problem persisted. We are still investigating. Otherwise no known problems.

Medicina (Andrea Orlati at Thu May 31 14:00:07 2007) Success :

All ok.

Westerbork (Tony Foley at Thu May 31 14:37:00 2007) Minor failures : PHAS

Wb used in phased array mode. For some reason there is no sign of observing the second source (4C39.25) in the array output. I am very puzzled.

Urumqi (Wenjun Yang at Thu May 31 15:16:05 2007) Failure : RECE

The compressor of C-band doesn't working.

Shanghai (Bo Xia at Fri Jun 1 01:42:13 2007) Success :

Torun (K. Borkowski at Fri Jun 1 05:32:07 2007) Minor failures :

JIVE has detected swapped polarizations. This was corrected immediately.

Westerbork (Tony Foley at Fri Jun 1 08:19:08 2007) Minor failures : PHAS

Wb used in phased array mode. Problem found for 4C39.25; the fringe pointing was done correctly, but the telescopes never moved off DA193. We have not yet found the cause, but a disk on our fileserver died last night and has been behaving oddly for a few days. We are reconfiguring and restarting all systems now (1 Jun 08UT)

Noto (P. Cassaro at Sun Jun 3 09:56:56 2007) Success :
