No known problems
Effelsberg (A. Kraus at Fri Mar 1 11:36:52 MET 2002) Minor failures
As suggested by MAG, only the first tape was recorded. Between
UT1500-1535 we had to stop due to strong wind. The caltemp was by
mistake set to the wrong value of 7.0 (instead of 2.5), hence the tsys
values delivered by the FS are too large. This was fixed at UT1545.
VLBA (Tony Foley at Fri Mar 1 12:05:05 MET 2002) Failure
MAJOR problems with mosaic mode (only the first 2 scans ran ok).
After that we got stuck on j0605+4030.
The problem was traced to a buffer overflow in software reading
the VEX file with 16 channels.
When we attempted a restart the delay control had stopped working!
We are sending the tapes anyway to check dual head and whatever can
be made of the weak source.

Yebes (Paco Colomer at Sun Mar 3 07:50:15 MET 2002) Minor failures
Many problems with antenna control. Only one thin tape recorded
(as suggested by MAG). Very few scans on it may have good data.
