Experiment Feedback

Medicina (g.Maccaferri at Wed Jun 6 06:06:08 2007) Success :

Onsala (Michael Lindqvist at Wed Jun 6 06:27:19 2007) Minor failures :

1. We had a few "record pointer not incrementing" from the Mark5 software. FS reported no errors though. We have saved the Mark5 log. 2. FS clock: We got "setcl: formatter to FS time difference 0.5 s". Took some time before the operator saw that and used the command sy=run setcl offset &.

Torun (K. Borkowski at Wed Jun 6 06:48:24 2007) Success :

No known problems (save, of course, RFI, which are a sort of norm).

Hartebeesthoek (Jonathan Quick at Wed Jun 6 07:51:31 2007) Minor failures : HIGH

Heavy rain expecially towards the end of experiment

Westerbork (Tony Foley at Wed Jun 6 11:17:11 2007) Minor failures : RFI

Wb used in phased array mode. RFI started at low level but became very strong during the run. The array data will be difficult to calibrate.

Effelsberg (A. Polatidis at Fri Jun 8 09:32:38 2007) Minor failures :

Started with slightly warm receiver, Tsys was around 10K higher than normal in the first couple of hours. The receiver temperature stabilised after the first two hours. Lost scans 2147-2208 due to long drive to pointing source
