General Comments. ( Brief data summary and scan listing )
EP055 had 10 stations, 8 16MHz IFs, and two polarizations. There were 16frequency points per IF/pol, and integration times were 2s. Considerably more information is included in the experiment's cover letter on the standard-plots portion of the EVN Archive. This data does not include the target cola199 & its reference source J2308+0946. In the pipelining, only the phase-reference sources and fringe-finders were fringes; all the cola* targets were phase-referenced from their appropriate phs-ref sources. The SOLINT was set to the scan lengths for the phs-ref sources (2min).

The EVN reliability indicator (ERI) for this experiment was ERI = 0.898 . ERI* = 0.898 . The ERI was 0.898. The losses include Wb missing IF8, Nt missing IF7-8 LCP (taken as 7/8 of a station). Lack of Cm signal in IFs 1-2,5-8 was considered as a known loss due to the limits of the micro-wave link (counts as 1/8 of a station that was always present). No penalty was assigned to the splitting of its available 16MHz bandwidth between two 16MHz IFs. Temporal losses include 33.5min for Jb, 31.5min for Nt, and 2.6hr for Ef (25s early scan-end * 476 scans). The total time was taken as the time in scans (17.25hr), not counting recording gaps.

Plots of the autocorrelations
Comments.
745 pages, each scan plotted separately, all stations. The missing IF/pols are evident (each station has separate plots per polarization in each scan).

plots of the uncalibrated amplitude and phase against time
Comments.
45 pages, full-experiment for Ef-* baselines, no calibration applied. A 1min plot-averaging was used. Amplitude scales dominated by the fringe-finders.

Plots of the uncalibrated amplitude and phase against frequency channel
Comments.
622 pages, 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.

TSYS against time
Comments.
16 pages, TY1 table, each IF/pol on a separate plot. The period around 02-03UT on the second day correspond to generally lower elevations.

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.
16 pages, gain amplitude from CL2 table.

Fringe-fit phase solutions (including Parallactic Angle correction).
Comments.
15 pages, CL3 station phase solutions -- CL3 = CL2+SN2, thus also includes the initial amplitude/parallactic angle calibration from CL2 and the fringe solutions from SN2. Ef is the reference station; it's plot shows the effect of the parallactic angle correction (not a smooth curve, of course, since the schedule moves about on the sky).

Fringe-fit delay solutions
Comments.
15 pages, SN2 station delay solutions for the fringed sources, each IF/pol on a separate plot. Outliers (multiples of ~200ns) in some stations/IF/pols: IF1/L (all sta), Cm IF3, On IF5/R, Ur IF1. Nt IF7/L has one unflagged solint (no real data here).

Fringe-fit rate solutions
Comments.
15 pages, SN2 station rate solutions. Generally smaller outliers, concentrated in Nt & Tr.

Telescope bandpasses
Comments.
3 pages, bandpass table 1. Only the fringe-finders were used for bandpass calibration (DA193, 3C39.25, 3C286, J2005+7752).

Calibrated amplitude and phase against time (a priori amplitude calibration and fringe-fit solutions applied).
Comments.
36 pages, full-experiment for Ef-* baselines, calibrated with CL3. The 1-min plot-averaging still applied. More phases seen lined up ~0, but the amplitude scale is still dominated by the fringe-finders.

Calibrated amplitude and phase against frequency channel
Comments.
622 pages; Ef-* baselines calibrated with CL3 and BP1.

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

Comments.
15 pages; CL4 gain-amp. All stations seem reasonably close to the square-root of their SEFD listed in the EVN status table.
