General Comments. ( Brief data summary and scan listing )
P band (92 cm) network monitoring experiment (NME) observed on 3 June 2011. The data rate was 256 Mbps (4 x 8 MHz subbands, dual polarization, two-bit sampling). The experiment observed four sources 3C84, B0329+54, 3C120 and B05321+21. 3 stations participated in the experiment: Ef (DBBC backend), Jb1 and Wb. There were fringes to Ef and Wb stations, but none to Jb. Either Wb or Ef had swapped pols, but since there was only one baseline in this experiment, the station responsible for this cannot be determined without looking at other experiments in the session.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.33 (No Jb) . ERI* = 0.33 .

TSYS against time
Comments.
Very high and noisy Tsys for Ef in all IFs (on the order of Kilo Kelvin), no useful Tsys in IF 4L, and probably in the other IFs too. Nominal values should be used for Ef.

Telescope sensitivities from the a priori TSYS and Gain curves (the square of this number gives the antenna noise (SEFD) in Jy - the smaller the better).

Fringe-fit phase solutions (including Parallactic Angle correction).
