General Comments. ( Brief data summary and scan listing )
C band NME observed on 20 Oct 2008 (session 3/2008). 256 Mbps, 2-bit sampling, dual polarization. There were 4*8 MHz channels in both RCP and LCP. The experiment started with J1800+3848, then continued with phase-referencing between 3C454.3 and J2254+1341.
9 stations participated. ON stopped the observations due to strong winds. JB has no fringes probably due to clock jumps.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.54 . ERI* = 0.73 . (JB=0, Ef=1, Wb=1, On=0, Nt=1, Mc=0.78, Tr=1, Ur=1, Sh=1)

Cm: good data are on IF2 and IF3. All IFs and the lower channels of IF and the upper channels of IF3 will need to be flagged.

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).
