Medicina (zacchiroli at Mon Mar 3 12:24:34 EST 1997) Success
Onsala (Antonis Polatidis at Mon Mar 3 17:22:51 EST 1997) Failure
Due to very high winds we were not able to observe at all. Sorry !
Effelsberg (dgraham at Tue Mar 4 03:06:38 EST 1997) Minor failures
Westerbork (Tony Foley at Tue Mar 4 07:09:52 EST 1997) Minor failures
Problems with the telescope pointing computer
caused loss of scans at 0938-0951UT and 1504-1513UT.
There was also an intense GLONASS interference
covering the whole band at about 1030UT.
Shanghai (Huang Xinyong at Wed Mar 5 05:29:28 EST 1997) Success
Clock offset = 0.66-0.67 msec. No problems, weather fine.
Jodrell (Alastair Gunn at Tue Mar 18 15:50:34 MET 1997) Success
No major problems. Very bad interference.
Cambridge (Alastair Gunn at Tue Mar 18 16:01:44 MET 1997) Minor failures
Late on source due to FS problems at start of experiment - first
target missed. FS re-started at 13:40, data lost for probably
half an hour prior to this. IF A and C swapped at 09:53 to extend
band. Prior to this a limited band was being recorded (Cambridge
IF link into VLBI is very complex). Please ignore TRACKING SLEWING
errors - Cambridge FS not connected to data link.
Calibration (Fredrik T Rantakyro at Thu May 8 11:36:20 METDST 1997) Success
The ANTAB file for the experiment has been placed on VLBEER in the
Feb97 directory with the name em25b.antab. This file contains the
preliminary calibration results and may be updated when I receive
updated information from the telescopes and the results from the
datareduction of the calibration experiments.
MPIfR (Walter Alef at Wed Jan 7 12:15:03 MET 1998) Minor failures
Crimea, Onasla and Noto did not observe. Wrong pol at Urumqi. Lot of time lost at
Cambridge. Rest: standard recording problems (sse CAL).
