Experiment Feedback

Medicina (T. Venturi at Fri Sep 19 23:28:19 METDST 1997) Minor failures

First 45 minutes lost because of problems at the antenna. Otherwise the experiment ran smoothly without apparent problems.

Torun (K.Borkowski at Sat Sep 20 23:09:41 METDST 1997) Success

Effelsberg (dgraham at Mon Sep 22 09:11:22 METDST 1997) Minor failures

PI underestimated acceleration time. 6 degree drive to reference source took up to 50 sec, so only 10-15 sec on source. Better at low elevation.

Noto (C.Trigilio at Mon Sep 22 16:51:53 METDST 1997) Success

Westerbork (Tony Foley at Tue Sep 23 17:21:36 METDST 1997) Minor failures

Read headstack sometimes stuck and telescope not yet onsource at start of observation (slews were too fast)

Cambridge (Alastair Gunn at Tue Sep 23 22:00:51 METDST 1997) Success

No known problems. Possible erroneous SLEWING error messages and tape motion error messages.

Calibration (Fredrik T Rantakyro at Wed Nov 5 15:46:52 MET 1997) Minor failures

The ANTAB formatted TSYS information can be found on VLBEER in the SEP97 directory. The file is called gl021b.antab and contains the latest antenna calibration information.
