Experiment Feedback
Medicina (Vargiu at Mon Feb 10 00:11:41 2003) Success :
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
final scans.
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.
(See DR#M101405)
6) Sources of scans 157, 176 and 231 were lost due to the
communication problem between EAC and the DSS63 antenna.
