General Comments. ( Brief data summary and scan listing )
ER026D had 9 stations, 8 8MHz IFs, and two polarizations. There were four passes; this pipelining corresponds to the geodetic pass, with 32 frequency points per IF, 2 pols, 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 1.5 minutes. Ef & Ys were used as the reference stations.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.934 . ERI* = 0.934 . The ERI for the geodetic pass was 0.934. Losses include Jb having no fringes in the IF3-4/LCP in the geodetic mode, and Tr having no fringes in IF5-6/LCP. Only EVN stations contributed to the ERI calculation (no accounting for Vm). The ERI and ERI* for the whole experiment, weighted by time over all passes were 0.922.


Plots of the autocorrelations
Comments.
Each scan plotted separately, all stations.


plots of the uncalibrated amplitude and phase against time
Comments.
Full-pass for Ef-* & Ys-* baselines, no calibration applied. A 1.5 minute plot-averaging was used.


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


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


TSYS against time
Comments.
TY1 table, each IF/pol on a separate plot. Each pass has its own edited a antab file, with INDEX lines reflecting the IF(s)/pol present in it data. Vm had dummy Tsys, with DPFU in the antab file to reflect an SEFD of 400 Jy (Vm not in any geodetic-mode scan).


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. For this experiment, one lag corresponds to 1/16 microsecond of delay.


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


Telescope bandpasses
Comments.
Bandpass table 1. 3C345, 0555+394, 0927+390, and 2148+065 were used for bandpass calibration.


Calibrated amplitude and phase against time (a priori amplitude calibration and fringe-fit solutions applied).
Comments.
Full-pass for Ef-* & Ys-* baselines, calibrated with CL3. The 1.5-min 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.
