General Comments. ( Brief data summary and scan listing )
EP088E had 12 good stations, 8 16MHz IFs, 4 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. In the pipelining, the target sources were treated as phase-reference targets and were not separately fringe-fit. The SOLINT was set automatically to a value commensurate with a typical reference-source scan. Ef was used as the reference stations.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.82 . ERI* = 0.82 . The losses include : Jb: incorrect LO, no useful data; Tr: lost first 41min; Sr: FILA10G loss of sync, lost data in ranges 09:32 - 10:36 and 14:40 - 15:00; Sv: Missing scans No0098-99no fringes to Nt and Tr having no fringes in IF7-8/RCP. // (Ef=1, Wb=1, Jb=0, On=1, Nt=1, Tr=0.94, Sv=0.99, Zc=1, Bd=0, Sh=1, Hh=1, Sr=0.88).


Plots of the autocorrelations
Comments.

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 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.


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


Telescope bandpasses
Comments.
Bandpass table 1. 3C454.3, J1740+5211, J1824+5651, J2327+0940, J0152+2207, J1302+5748, J1302+5748 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.


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.
