Experiment Feedback

Noto (C.Trigilio at Mon Sep 27 11:37:58 METDST 1999) Success

Medicina (Sergio Mariotti at Mon Sep 27 11:56:11 METDST 1999) Success

Nothing to say

Torun (K.Borkowski at Mon Sep 27 14:34:29 METDST 1999) Success

Little more than 1 min. lost beginning at 0:07:30 due to a long slew around the azimuth axis to a new source.

Effelsberg (A. Kraus at Tue Sep 28 10:50:16 METDST 1999) Minor failures

Some scans were missed because of insufficient slewing time. Apparently, we had some problems with the thin tape on the VLBA4 recorder (many parity errors).

Jodrell (Alastair Gunn at Wed Sep 29 13:34:08 METDST 1999) Failure

The Lovell telescope had been transferred to another program in the break before this experiment, and the LO/IF settings not returned to their correct values. All data therefore useless.

Calibration (Jean\-Francois Desmurs at Sun Nov 7 15:56:13 MET 1999) Minor failures

The ANTAB formatted file for this experiment can be found on VLBEER in the sep99 directory under the name: ep027b.antab. Read the comments in the file to get further information (Rem : Jb bad Tsys values.)

JIVE (Bob Campbell at Wed Mar 1 08:56:57 MET 2000) Minor failures

No Jb or Tr throughout -- hence 5 stations.

Wb tracks 7,9,10,15 marginal --> RCP 3rd subband, LCP 1st & 3rd subband could be suspect (arising from the interplay between subband/polarization channels & their constituent tracks via fan-in).

aips++ plots given to Co-Inv. during visit to JIVE: all weight(t), amp(lag); selected amp(t), phs(t), amp(frq).
