Experiment Feedback

Onsala (Michael Lindqvist at Mon Jun 9 07:21:53 2003) Minor failures : WIND

Antenna stowed 04:55 UT due to high winds.

Hartebeesthoek (Jonathan Quick at Mon Jun 9 07:57:31 2003) Minor failures : LATE

Scan no0003 - late onsource due to repair of antenna drive fault

Medicina (Andrea Orlati at Mon Jun 9 09:18:30 2003) Minor failures : FS

Field system crashed at start. Lost first two scans.

Torun (K.Borkowski at Mon Jun 9 12:45:07 2003) Minor failures : RECE

RCP receiver was unstable intermittently since 22:20. Somewhere between 20:12 and 21:12 UT our hydrogen maser lost the lock! Till midnight timing of 1pps against the GPS stayed about normal. Later we don't have information because a control program failed to store the data, but by 6:20 UT on day 160 the maser clock drifted to +1470 us (to reach 2850 us at 12:30).

Jodrell_Bank (Alastair Gunn at Tue Jun 10 13:02:31 2003) Success :

No known problems. Ran under MERLIN control.

Cambridge (Alastair Gunn at Tue Jun 10 13:04:34 2003) Success :

No known problems. Ran under MERLIN control. Sometime in the early morning of day 160 the subreflector stalled and did not recover. However, we believe this happened after the end of en001, so the data should be good.

Effelsberg (A. Kraus at Wed Jun 11 09:10:03 2003) Minor failures :

Last scan lost by mistake.
