Medicina (orfei at Sun Oct 19 09:47:31 2008) Success :
Urumqi (Hua Zhang at Mon Oct 20 02:42:35 2008) Failure :
The receiver Lo is wrong for gw019b.skd.In fact,The Lo is 8100MHz,it is not 8080MHz.
I am sorry, because I am not find wrong in time.
Yebes (Pablo de Vicente/Rebeca Soria at Mon Oct 20 09:21:30 2008) Minor failures : RECO
Rain during part of the observation
Mark5B hung at 01:30 approx. and I had to restart completely the
computer because I could not switch off the disk pack. This failure
might be related to the fact that I extracted the full disk pack in
bank A and inserted a new one (without turning the key) by then.
After rebooting I extracted the disk pack with only 90 minutes of
data and inserted a new one.
At 6:00 the disk bank switch was not automatic and had to be done
manually.
The disk pack I extracted and with partial information has been
tested this morning and is correct.
Effelsberg (Uwe Bach at Mon Oct 20 09:23:09 2008) Success :
Arecibo (T. Ghosh at Tue Oct 21 12:25:26 2008) Success :
Westerbork (Geert Kuper at Wed Oct 22 21:10:53 2008) Minor failures : PHAS FS
Wb used in phased array mode.
X/Y phase difference not optimal. We also had to resync the fs time
a couple of times, because the fs computer clock was synced by our ntp server but the 'rate model' was still on.
Robledo (Esther Moll at Thu Oct 30 15:12:03 2008) Success :
1. Formatter was on sync.
2. No antenna problems, all sources tracked.
3. SR properly tracking
4. Mark5 recorder#1 performance OK. All scan_check correct.
1932787995096 bytes of data recordedon WSRT-032/2000/1024 module.
1954244354040 bytes of data recordedon WSRT-064/2000/1024 module.

5. All video converters were affected by rain from 02:47UT until EOT.
6. Phase cal tones on. No anomalies observed.
7. Only one noise diode can be configured from EAC; only X-band LCP Tsys monitoring provided.
Antabfs file generated. Log and antabfs file transferred to vlbeer.
8. gps-fmout provided at experiment log.
Noto (P. Cassaro at Mon Nov 3 09:25:06 2008) Minor failures : TSYS
THe bbc#8 has been in overflow during a long part or the experiment.
