Experiment Feedback

Medicina (mauro at Sat Feb 18 21:33:27 2006) Minor failures : WIND

There is some antenna tracking problem for hight wind speed. Partial cloudy

Westerbork (Tony Foley at Mon Feb 20 10:28:53 2006) Minor failures :

Wb used in phased array mode. Array needed a reboot just before observations because of errors in the 5th IVC band. The label on 1 disk pack was wrong (had StreamStor1 in stead of WSRT-057) so it was edited when the schedule ended.

Robledo (Cristina Garcia-Miro at Mon Feb 20 12:39:14 2006) Success :

Overcast. At 15:25UT started raining. Three modules recorded: WSRT-005, WSRT-017 and OSOD-019. gps-fmout=+4.631E 10-7 (at start), +5.276 10-7 (at end).

Hartebeesthoek (Jonathan Quick at Mon Feb 20 22:45:51 2006) Success :

No known problems

Effelsberg (A. Polatidis at Tue Feb 21 12:01:57 2006) Success :

Raining at times. Missed two scans on J0028+20 (1248-1250 and 1749-1750) for pointing measurements

Arecibo (E. Momjian at Fri Feb 24 16:13:15 2006) Success :

Noto (P. Cassaro at Thu Mar 2 00:06:17 2006) Minor failures : FORM ANT

Or at least we hope they are 'minor'. The formatter gave synch errors all the time, but there is no trace in the log file. It has been impossible to fix it, each begin of scan the error returned. We suspect that it was a false error, it is worth to check. From about 17:40 UT to the end the antenna has apparently worked correctly, even if in the log is reported a 'slewing' error. It must be checked before flag the data with the 'flagr' informations.

Torun (Kaz Borkowski at Mon Feb 20 11:25:29 2006) Minor failures : PCAL

Tr phase cal system failed to produce signals during all the 6 cm experiments for yet unknown reason.

Westerbork (Tony Foley at Fri Feb 24 15:48:24 2006) Minor failures : ANT POIN

The feedback from the antenna control for SINGLE-DISH observations is unreliable for 20seconds after a source change. We will try to fix this. (Affected only the 5cm experiments -Z.P.)
