Experiment Feedback

Onsala (John Conway at Mon Feb 19 08:04:08 EST 1996) Minor failures
Phase-cals switched off (unit malfuntioned causing large signal strengths increasing Tsys in some channels). No other know problems.

Jodrell (Dave Henstock at Thu Feb 22 06:23:40 EST 1996) Minor failures
Bad interference during experiment (especially VCs 9,10, but also 13). Due to RFI, Tsys measurements only crudely calibrated. Specific problems: Day 41 ~22.45-23:13 and 23:45-00:12 Field System crash - scans between these times will have been lost Day 42 01:40-02:50 Telescope apparently off-source (unknown reason). Tsys is in Jy, need to multiply measured Tsys by 1.23 for better calibration.

Medicina (Venturi Tiziana at Thu Feb 22 09:44:44 EST 1996) Success
Experiment carried out successfully. Apparently no problems reported.

Noto (Corrado Trigilio at Sat Feb 24 06:09:37 EST 1996) Success
No problems, apart some offsource for power fail (few minuts in total). Please use the corrected Tsys values that I will provvide.

Westerbork (foley at Mon Feb 26 11:40:55 EST 1996) Success

Calibration (Fredrik T Rantakyro at Thu Sep 26 10:09:46 EDT 1996) Minor failures
