Experiment Feedback

Onsala (John Conway at Mon Feb 19 08:14:34 EST 1996) Minor failures
Phase cals switched off since malfunction causing high powers in some channels were affecting Tsys values. Antenna problem causing low slew speed when moving East meant that one or two scans were missed.

Simeiz (Alexandre Volvatch at Wed Feb 21 08:24:52 EST 1996) Minor failures
30 passes (04:33-05:07, 10:17-12:05, 14:45-17:19, 22:00) were omited because we had not power (switch off). 1 pass (22:15) were omited because source was behind the hill(EL=3d).

Cambridge (Dave Henstock at Thu Feb 22 06:34:58 EST 1996) Minor failures
Note there are no Tsys measurements for Cambridge. There is a strong possibility that Cambridge formatter clock was wrong by up to 6 seconds (not noticed until day 44). Specific Problems: Day 43 07:01-07:22 and 08:50-09:07 and 11:51-12:00 and 20:30-22:30(?) Field System crashed. All or most of scans between these times will have been lost. 12:55 Possible tape problem. Tsys is 212 Jy (from EVN status).

Jodrell (Dave Henstock at Thu Feb 22 06:38:35 EST 1996) Minor failures
Bad RFI during experiment in VCs 9,10 and occasionally VC 7. Due to RFI the Tsys measurements will only be crudely calibrated. Specific Problems: Day 43 14:18(?)-14:35 and 15:50-16:10 Field system crashed; scans between these times will have been lost. 16:10-19:07 Off-source due to high winds. 23:57 Late on source due to slew Tsys is in Jy, need to multiply measured Tsys by 1.23 for better calibration.

Medicina (Venturi Tiziana at Thu Feb 22 09:54:24 EST 1996) Success
The experiment was carried out successfully.

Noto (Corrado Trigilio at Sat Feb 24 06:21:49 EST 1996) Minor failures
Bad weather conditions, strong rain, some power failures. Corrected Tsys values will be provvided.

Westerbork (foley at Mon Feb 26 11:43:03 EST 1996) Minor failures
lost 04:33-0630 UT (quadrant safety limit). ~16% reduced sensitivity 03:30-08:30 UT (9Y fringe card dead).

Calibration (Fredrik T Rantakyro at Thu Sep 26 10:09:14 EDT 1996) Minor failures
