General Comments. ( Brief data summary and scan listing )
6cm phase-referencing experiment, observed on 2 Jun 2007. Data rate was 128 Mbps (2 X 8 MHz subbands, dual polarization, two-bit sampling). The target source '1045+352' was calibrated using the phase-reference source 'J1104+3812'. '3C286', 'OQ208' and 'J0927+3902' were also observed as calibrators/fringe-finders.
8 stations participated. Cambridge (Cm) had a formatter problem and produced no fringes throughout the experiment (autocorrelations are also bad). All Cm data will need to be flagged.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.71 . ERI* = 0.71 . (JB=1, WB=0.95, Ef=1, ON=1, MC=1, TR=0.9, NT=1, CM=0)

The uncalibrated amplitude and phase of the crosshand correlations against frequency channel (not available)
Comments.

TSYS against time
Comments.
Mc reported some thunderstorms, probably the cause of the Tsys variations seen in the early part of the experiment.

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 phase solutions (including Parallactic Angle correction).
Comments.

Fringe-fit delay solutions
Comments.

Fringe-fit rate solutions
Comments.

Telescope bandpasses
Comments.
Jb: No solution for IF1 LCP. Maybe due to some unedited bad data?

Calibrated amplitude and phase against time (a priori amplitude calibration and fringe-fit solutions applied).
Comments.
Some data in the middle of the experiment have been flagged - more careful editing probably needed before calibration.
