General Comments. ( Brief data summary and scan listing )
The SOLINT was set at 1.0 min. Mc and Ef were used as reference stations. The fringe-finder and bandpass calibrator were 'OQ208', 'J1159+2914'.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.80 . ERI* = 0.91 . (EF=0.4/1, WB=0.88/0.88, JB=1/1, O8=1/1, MC=1/1, TR=1/1, SH=1/1, HH=1/1, SV=0.88/0.88, ZC=0.88/0.88, BD=0.88/0.88)- SV, BD, ZC had problem with the GAIN CURVE of IF8.

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

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

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

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

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. Jump in Tr.

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. OQ208 and J1159+2914 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-* and Mc-* baselines, calibrated with CL3.

Calibrated amplitude and phase against frequency channel
Comments.
Ef-* and Mc-* baselines calibrated with CL3 and BP1. The amp and phaseplots self-scale, not necessarily going down to 0 in the case of the amps. MC IF1 has some problem.
