Experiment Feedback

Medicina (morsiani at Wed May 28 14:58:54 2003) Success :

Effelsberg (A. Kraus at Wed May 28 18:18:43 2003) Success :

Shanghai (Xinyong Huang at Thu May 29 01:30:45 2003) Failure :

Sorry, Seshan station not observation this experiment. Because of the part of the electrocircuit control board of the antenna's azimuth and elevation were burned out a few days ago. Now have't yet finished the repair.

Onsala (M. Lindqvist at Thu May 29 03:37:30 2003) Success :

No known problems

Urumqi (yangwj at Thu May 29 03:59:00 2003) Success :

Torun (K.Borkowski at Thu May 29 05:55:46 2003) Success :

No real problems, but there were quite a few warnings of the late on source case.

Hartebeesthoek (Jonathan Quick at Thu May 29 08:04:00 2003) Minor failures : TSYS RFI

Severe impulsive RFI across the band, plus a spike in one of the VCs resulted in many false Tsys readings

Noto (P. Cassaro at Fri May 30 09:15:11 2003) Success :

Cambridge (Alastair Gunn at Sun Jun 1 14:13:25 2003) Success :

Single polarisation selected for last two passes to check Cambridge setup. No known problems.

Urumqi (Liu Xiang at Tue Jun 3 12:52:31 2003) Minor failures : TSYS FS

Comment: the lowest Tsys of BBCs in logfile (like 22K at LCP, 12K at RCP) should corresponds to 22K at LCP and 22K at RCP as we measured with radiometer, the FS has someproblem with Tsys measure. so you could use a correction factor from above in ANTAB.

Westerbork (foley at Mon Jul 7 15:26:17 2003) Minor failures : PHAS

RTB replaced. Used 13 telescopes in the array
