Experiment Feedback

Westerbork (Tony Foley at Wed Jun 2 08:15:51 2004) Minor failures : HA-E RFI

Wb used in phased array mode. Had to stop at 06:08UT as all sources after that are out of Hour Angle limits. Severe RFI about 1242MHz - it took several attempts to phase that part of the band up.

Onsala (Michael Lindqvist at Wed Jun 2 14:39:19 2004) Failure : RFI

Failure?? Severe RFI across the IF-band. Large changes on the VC levels.Very strong RFI at 1298 MHz. Bad Tsys values.

Effelsberg (A. Kraus at Thu Jun 3 10:21:52 2004) Minor failures : TSYS LATE RFI

Accidentally, a wrong setup was chosen. All data before UT0336 lost. Due to severe RFI and insufficient slewing times, many tsys measurements are bad.
