General Comments. ( Brief data summary and scan listing )
ED035A was observed in an e-VLBI run on April 12 2011, had 9 stations Ef Jb Mc On Tr Wb Ys Hh Sh and observed at a datarate of 1 Gbps Considerably more information is included in the experiment's cover letter on the standard-plots portion of the EVN Archive. In the pipelining, the target sources were treated as phase-referenced sources and not directly fringed. The SOLINT was set automatically at a representative length of a reference-source scan in a phase-reference cycle (60s judging from the schedule). Ef & Tr were used as the reference stations (Tr for the time that Ef was stowed).

The EVN reliability indicator (ERI) for this experiment was ERI = 1 . ERI* = 1 .

Plots of the autocorrelations
Comments.
Each scan plotted separately, all stations. Noisy Autocorrelations in IF 3 of Ys

plots of the uncalibrated amplitude and phase against time
Comments.
Full-experiment for Ef-* baselines, no calibration applied.

Plots of the uncalibrated amplitude and phase against frequency channel
Comments.
Scalar averaged Ef-* baselines, each scan plotted separately. No calibration applied yet.

The uncalibrated amplitude and phase of the crosshand correlations against frequency channel
Comments.
Scalar averaged Ef-* baselines for LR, each scan plotted separately. No calibration applied yet.

TSYS against time
Comments.
TY1 table, each IF/pol on a separate plot. Tsys for Jb in LCP IF 7 and 8 are high (300-400K)

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.
Gain amplitude from CL2 table.

Fringe-fit phase solutions (including Parallactic Angle correction).
Comments.
CL3 station phase solutions -- CL3 = CL2+SN2, thus also includes the initial amplitude/parallactic angle calibration from CL2 and the fringe solutions from SN2.

Fringe-fit delay solutions
Comments.
SN2 station delay solutions for the fringed sources, each IF/pol on a separate plot.

Fringe-fit rate solutions
Comments.
SN2 station rate solutions.

Telescope bandpasses
Comments.
Bandpass table 1. J1157+1638, J1241+5458, J1504+1029, J1112+0724, J1235+3621, J1358+1119 were used for bandpass calibration.

Calibrated amplitude and phase against time (a priori amplitude calibration and fringe-fit solutions applied).
Comments.
Full-experiment for Ef-* baselines, calibrated with CL3. Cross correlation amplitudes for Ys in IF3 are low.

Calibrated amplitude and phase against frequency channel
Comments.
Ef-* baselines calibrated with CL3 and BP1. The amp and phaseplots self-scale, not necessarily going down to 0 in the case of the amps.
