General Comments. ( Brief data summary and scan listing )
EG058C, C-band e-VLBI run on 2012 Jan. 11. Participating telescopes were Jodrell Bank (MkII), Westerbork, Effelsberg, Onsala, Medicina, Torun , Hartebeesthoek, Shanghai and Arecibo. Yebes could not take part because of a Makr5B problem. Westerbork died before the second part with Ar started.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.75 . ERI* = 0.81 . (Ef=0.75, Jb2=1, Mc=1, On=1, Tr=0.88, Wb=0.5, Hh=1, Sh=0.75/1, Ar=1)

Plots of the autocorrelations
Comments.

plots of the uncalibrated amplitude and phase against time
Comments.
Wb: dead in the second part
Sh: coming back from a network outage in the begining od EG058C.

Plots of the uncalibrated amplitude and phase against frequency channel
Comments.
Ef: DBBC problems; used Mark5A on MkIV rack, but this limited the data rate to 768 Mbps.
Tr: IFs L5-6 missing (BBC#6 dead)

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

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 phase solutions (including Parallactic Angle correction).
Comments.

Fringe-fit delay solutions
Comments.

Fringe-fit rate solutions
Comments.

Telescope bandpasses
Comments.

Calibrated amplitude and phase against time (a priori amplitude calibration and fringe-fit solutions applied).
Comments.

Calibrated amplitude and phase against frequency channel
Comments.
Ef: amplitude jump near the end of the first part (1:45 UT) looks like due to an error in antab file (jump in Tsys)
