Medicina (C. Bortolotti at Mon May 26 15:35:37 METDST 1997) Minor failures
Lost the scans from start, untill 146-08:12:30 for wrong L.O. value. sorry. Lost the scan from 146-12:04, untill 146-12:30 for soft elevation limit.
HartRAO (Jonathan Quick at Wed May 28 09:29:48 METDST 1997) Minor failures
Lost scans from 18:00 - 21:06 (all source below horizon anyway) due
to emergency antenna repairs. Lost start of scan at 22:41 and 04:41
due to tape drive failing to start and end of scan 01:33 due to
resultant tape psotion problems +- 30s each. Lost all scans after
10:42 due to hail damage from severe unseasonal thunderstorm.
Onsala (Antonis Polatidis at Wed May 28 14:35:32 METDST 1997) Minor failures
Started at 1933 UT due to our error and hence lost 1.5 hours.
However, on the distributed block schedule (version 2, April 28 and
ammended by the schedulers later email message), the starting time
for the experiment was 1930 UT.
Onsala (Antonis Polatidis at Wed May 28 14:36:22 METDST 1997) Minor failures
Please make sure that any such changes in starting times always
appear on the block schedule (although this was my fault since
I should have checked it).
Torun (K.Borkowski at Thu May 29 02:05:52 METDST 1997) Minor failures
Late start (19:07) due to a human error. New pointing corrections
introduced just before the beginning of the experiment contained
systematic errors, which might have considerably reduced the tracking
accuracy.
Jodrell (Alastair Gunn at Tue Jun 3 11:39:02 METDST 1997) Minor failures
FS crashed sometime after 11:00, restarted at 12:00, on source at 12:10.
Tape stopped and restarted at about 12:40. No other known problems.
Calibration (Fredrik T Rantakyro at Mon Jul 21 14:03:44 METDST 1997) Minor failures
The ANTAB file for the experiment can be found on VLBEER in the MAY97 directory
with the name GB26A.ANTAB. The file is ready to be used with the AIPS tasks
ANTAB/APCAL. Read the ANTAB file for any specific comments regarding this experiment.
The ANTAB File contains all avaliable calibration information, but not
all EVN antennas has calibration information for 5cm experiments.
MPIfR (Walter Alef at Wed Jan 7 11:46:34 MET 1998) Failure
Correlation cancelled due to MK4 formatter bug: 500 kbit sampling rate does not work.
