General Comments. ( Brief data summary and scan listing )
C band phase-referencing experiment, observed on 16 Jun 2009. Data rate was 512 Mbps (8 X 8 MHz subbands, dual polarization, two-bit sampling). The target source NGC6240 was calibrated using the phase-reference source J1651+0129. '3C345' was the fringe finder. The target source NGC6240 was successfully detected in our crude map.

10 stations participated. No fringes to the Yebes telescope due to failure of the H-maser. Shanghai had low amplitude in IF 5-8.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.8 . ERI* = 0.8 . (Ef=1, Mc=1, On=1, Jb=1, Ur=1, Tr=1, Ys=0, Nt=1, Wb=1, Sh=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.

Fringe-fit delay solutions
Comments.
Sh: there was a delay diffence (~90 ns) between IF 1-4 and IF 5-8.
