General Comments. ( Brief data summary and scan listing )
C-band NME observed on 17 June 2006 (session 2/2006). 256 Mbps, 2-bit sampling, dual polarization and 8 MHz filters were used. 12 telescopes participated in this experiment. It started with 3C84 and 0234+285, followed by a phase-referencing between DA193 and J0605+4030.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.94 . ERI* = 0.94 . (TR=1, ON=1, MC=1, UR=1, SH=1, EF=0.74, WB=1, NT=1, CM=1, JB=0.92, HH=1, AR=1)

TSYS against time
Comments.

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).
Comments.
Shanghai appeared to be somewhat less sensitive than expected specially in the first part of the experiment, until 7:30 AM. The corresponding SEFD is 664 Jy (see the EVN Status Table).

Comments.
Very large corrections for Jodrell Bank (about a factor of two in Tsys).

Telescope sensitivities (the total AMP gain applied during both a priori and self calibration; the square of this number gives the antenna noise (SEFD) in Jy).
Comments.
The Onsala sensitivity was less than expected in the first scans, until 7:10AM (in all IFs and polarizations).
Urumqi had very low sensitivity IF1 (LCP) throughout the experiment.
Hartebeesthoek also had low sensitivity in IF1 (RCP) and IF2 (RCP) in the first two scans.
