General Comments. ( Brief data summary and scan listing )
C band phase-referencing experiment, observed on 11 Mar 2008. Data rate was 1 Gbps (8 X 16 MHz subbands, dual polarization, two-bit sampling). The target source IRAS2336 was calibrated using the phase-reference sources J2333+3901. Fringe finders were 3C286, 3C454.3 and 2134+004 was also observed as calibrator.
9 stations participated. Cm had a recording problem resulting to the loss of part of the data.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.95 . ERI* = 0.95 . (JB=1, EF=1, WB=1, CM=0.6, ON=1, MC=1, NT=1, TR=1, UR=1)

TSYS against time
Comments.
Jb and Cm did not measure Tsys, their nominal sensitivities were used instead.

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).
