Experiment Feedback

Onsala (John Conway at Mon Feb 19 08:21:42 EST 1996) Minor failures
Phase-cals switched off because malfunction caused them to increase Tsys in some channels. Occasional RFI just outside of observing band.

Jodrell (Dave Henstock at Thu Feb 22 06:58:39 EST 1996) Minor failures
RFI in observing band - particularly bad in VCs 9,10. Due to RFI Tsys measurements are only crudely calibrated. Specific Problems: Many scans have telescope late on-source due to slew. 00:13-00:31 Field system crashed and so scan(s) between these times will have been lost. Tsys is in Jy, need to multiply measured Tsys by 1.23 for better calibration.

Medicina (Venturi Tiziana at Thu Feb 22 10:01:47 EST 1996) Success
Apparently no problems.

Noto (Corrado Trigilio at Sat Feb 24 06:28:50 EST 1996) Success
No problems, apart some power failure (few minuts in total).

Westerbork (foley at Mon Feb 26 11:46:15 EST 1996) Success

Calibration (Fredrik T Rantakyro at Thu Sep 26 10:10:13 EDT 1996) Minor failures
