Experiment Feedback

Medicina (Orfei at Tue May 25 11:21:01 METDST 1999) Success
No problems

Torun (K.Borkowski at Tue May 25 11:22:38 METDST 1999) Success
Except for too low IF A level in the first minute of observations, no other known problems.

Westerbork (Tony Foley at Tue May 25 12:55:18 METDST 1999) Success
Source flux around 2.6Jy and SEFD of array (10 telescopes) around 55Jy. Polarizations should be about correct, but instrumental polarization could be ~10%. Playback reasonable on pass 1, but quite good on passes 2,3 and 4.

Onsala (A. Polatidis at Wed May 26 09:39:34 METDST 1999) Success
No problems. Parity errors reasonable, using 15 inch. vacuum with thick tape.

Noto (C.Trigilio at Wed May 26 13:58:36 METDST 1999) Success
No problem reported.

MPIfR (dgraham at Fri May 28 09:30:45 METDST 1999) Minor failures
Correlator report 27 May: Fringes to Jodrell2, Cambridge,WSRTArray, Torun, Onsala. Further details sent to VLBI Friends.

Jodrell (D.McKay at Fri May 28 13:37:54 METDST 1999) Success
We noted unusual noise in the recorder on the first pass only. This may have been a tape packing problem.

MPIfR (dgraham at Fri May 28 14:33:56 METDST 1999) Minor failures
corr report 28.5.: Medicina OK, VC5 still not working, probably USB/LSB problem as in feb session

MPIfR (dgraham at Tue Jun 1 11:27:40 METDST 1999) Minor failures
Correlator report 31stMay- tapes came from Noto and Shanghai. Noto OK, no fringes found to Shanghai.

Calibration (Jean\-Francois Desmurs at Fri Jun 18 19:30:27 METDST 1999) Success
