Urumqi (yangwj at Sun May 25 02:23:18 2003) Success :

Medicina (Franco Mantovani at Sun May 25 04:11:21 2003) Minor failures : LATE

The recording started a few minutes late due to antenna servo-system problems.

Onsala (Michael Lindqvist at Sun May 25 06:56:33 2003) Success :

No known problems.

Torun (K.Borkowski at Mon May 26 04:38:38 2003) Success :

No known problems.

Effelsberg (A. Kraus at Mon May 26 08:47:27 2003) Minor failures : WIND

Antenna was stopped because of a thunderstorm between UT2045-2123.

Hartebeesthoek (Jonathan Quick at Mon May 26 13:22:45 2003) Minor failures : RFI

Impulsive RFI seen at both polarisations

Noto (P. Cassaro at Tue May 27 12:07:37 2003) Minor failures : HA-E RFI

Severe RFI in the band The scan N. 10 has been lost due to antenna soft prelimit

Ops Crew: B/E; Weather condition: Clear; Station Time delay:+.5758; Recorder used: #1; L-band System Temp:23.5; L-Band Y-factor:11.11; Noise Diodes: ; Ambient Load:23.438; L-Band Coherency passed?

Urumqi (Liu Xiang at Tue Jun 3 12:48:16 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 some problem with Tsys measure. so you could use a correction factor from above in ANTAB.

Westerbork (foley at Mon Jul 7 15:08:59 2003) Minor failures : PHAS

RTB unreliable. Used 13 telescopes in the array. One of these (RT9) also had poor phasing
