Onsala (Michael Lindqvist at Mon Feb 10 10:06:10 2003) Success :
No known problems.
Noto (Pietro Cassaro at Mon Feb 10 11:40:40 2003) Minor failures :
In the final two hours of the experiment (from 22:00 UT)
we had some problems with the correction of the subreflector
position, so it is possible to have focus problems in the
Jodrell_Bank (Alastair Gunn at Mon Feb 10 14:47:20 2003) Success :
No known problems.
Cambridge (Alastair Gunn at Mon Feb 10 14:47:48 2003) Success :
No known problems. Please note that due to failure of headstack,
track 30 has been remapped to track 34, i.e. third system track.
Metsahovi (Ari Mujunen at Wed Feb 12 12:10:53 2003) Success : RECO
Tracks 19,27,29,31,33 are probably quite bad, otherwise
seemed to run okay.
Robledo (Z.P. (for Esther Moll) at Wed Feb 12 15:12:05 2003) Success :
Robledo (Z.P. (for Esther Moll) at Wed Feb 19 08:24:14 2003) Minor failures :
1) Level on video converters was stable during the whole experiment
2) Diode control worked for the whole activity
3) Full_cal procedure worked (of course only for LCP video
converters : 1, 3, 5 and 7 )
4) The formatter remained in sync.
5) During 4R pass the recorder#1 stopped at 6567 feet by
itself. As a result scan 120 data from 15:19Z to 15:27Z was lost.
Because of that pass 5F started from 6567 feet instead of 0 feet and
the end of tape was reached at 15:42Z (scan 138 data from 15:42Z to
15:50Z was also lost). At 15:46Z the 'tapepos=17600'
directive was entered and the tape was ready for scan 157.
6) Sources of scans 157, 176 and 231 were lost due to the
communication problem between EAC and the DSS63 antenna.
