No known problems
Westerbork (Tony Foley at Wed Jun 7 09:18:11 2006) Minor failures : RECE
Wb used in phased array mode.
The procedure files were wrong from the start (16:10) to 20:15
for BBCs 3-8. BBC 1 and 2 were OK. This was my mistake in editing
the procedures for the tied array setup; I edited "setup01" correctly but we only ran "setup02". This was spotted by the operator.
Scans from 20:15 should have the correct setup
We also had very strong RFI from 19:45-19:55
Effelsberg (dgraham at Thu Jun 8 11:23:26 2006) Minor failures :
At start very low in hills, antenna can hardly see source.
From tart until 17:42, track 11 defective. Formatter changed at 17:46.
From Start until 18:33 some internal interference spikes (e.g. 5MHz)
in VC02: swapped VC02 and VC12 at 18:33. Some RFI near 1647MHz at 19:30 and 04:20
Arecibo (C Salter/ T Ghosh at Wed Jun 14 14:28:22 2006) Success :
No Known problem

Jodrell_Bank (Alastair Gunn at Tue Jun 20 09:02:51 2006) Success :
The Lovell Telescope was used (Jb1).
Severl FS restarts required but no loss of data involved. No other known problems.

Torun (Kaz Borkowski at Mon Jun 5 12:32:29 2006) Minor failures :
This note concerns the UHF experiments only.
Shortly before the first experiment we could manage to install the Lange coupler to produce two circular polarizations instead of the linear polarization announced in the block schedule. Also, we failed to install the phase cal.
Jodrell_Bank (Alastair Gunn at Tue Jun 20 09:14:12 2006) Success : PCAL
The MkII telescope was used (Jb2).
During this session the Mk2 phase cal. signal was found to be too high and could not be easily reduced in strength. I therefore switched off the phas cal. signal for the entire session (for Mk2 only).
