General Comments. ( Brief data summary and scan listing )
GP051D had 17 good stations (no On) and two modes. This pipelining pertains to the geod mode, with 2 16MHz IFs, 2 polarizations, 32 frequency points per IF/pol, and 2s integrations. Considerably more information is included in the experiment's cover letter on the standard-plots portion of the EVN Archive. The SOLINT was set to 2.0 minutes. Ef, then Yy, were used as the reference stations.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.714 . ERI* = 0.714 . The ERI values pertain to only the EVN stations in the experiment, which included losing On entirely due to the declination motor casualty (here, I'm not counting the phase behavior in Tr/RR [cf the PI letter under standard plots] as a loss -- if we were, then the ERI would be 0.595).


Plots of the autocorrelations
Comments.
Each scan plotted separately, all stations. This plot seems not have been made (see instead the auto plots in the standard plots for representative passbands).


plots of the uncalibrated amplitude and phase against time
Comments.
Full-experiment for Ef-* baselines, no calibration applied. A 2.0-minute plot-averaging was used.


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 (not available)
Comments.
Scalar averaged Ef-* baselines showing LR, each scan plotted separately. No calibration applied yet.


TSYS against time
Comments.
TY1 table, each IF/pol on a separate plot.


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. Individual outliers dominate the y-axis scale for many station/IF/pol plots (no interactive SNSMO or SNEDT in the pipeline).


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


Telescope bandpasses
Comments.
Bandpass table 1. 2148+065, 2236+282, 0339-014, and 1746+622 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. The 2.0-minute plot-averaging still applied.


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

As above, but for the post-SPLIT table SN2.


Telescope sensitivities (the total AMP gain applied during both a priori and self calibration; the square of this number gives the antenna noise (SEFD) in Jy).
Comments.
CL4 gain-amp. The square of these values should provide the effective SEFD of the stations.
