General Comments. ( Brief data summary and scan listing )
C band phase-referencing Network Monitoring Experiment, observed on 23rd Nov 2006.
9 stations participated. Onsala suffered from high winds, Wb lost last scan, Ef had large pointing errors, Hb lost 2 scans, Tr had recording problems.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.91 . ERI* = 0.88 . (JB=1, ON=0.99, MC=0.99, NT=0.99, TR=0.99, UR=0.99, WB=0.96, EF=0.33, HH=0.99)

Plots of the autocorrelations
Comments.
Tr BBC 5 unlocked throughout experiment as reported by station. Otherwise OK.

plots of the uncalibrated amplitude and phase against time
Comments.
Wb was lost to high winds at 17:00, Ur fringe lost around 18:15. Torun problems as indicated on experiemental feedback.

Plots of the uncalibrated amplitude and phase against frequency channel
Comments.
Only Tr BBC5 problem. All others good.

The uncalibrated amplitude and phase of the crosshand correlations against frequency channel
Comments.
Good

TSYS against time
Comments.
Effelsberg arrived late. Onsala ended 17:00.

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.
Good, except for known problem with Tr BBC5

Calibrated amplitude and phase against time (a priori amplitude calibration and fringe-fit solutions applied).
Comments.
Hh phase calibration poor, On also not great.
