General Comments. ( Brief data summary and scan listing )
This part of EL032 comprised the observations of G78.12+3.63 and associated sources, with 8 stations, one 2MHz IF (DC edge 6667.70MHz), and two polarizations. There were 1024 frequency points, and integration times were 0.25s. Considerably more information is included in the experiment's cover letter on the standard-plots portion of the EVN Archive. In the pipelining, only J2007+4039, 3C345, and 3C454.3 were fringed. A SOLINT of 2.0min was used, and the individual integrations were UVAVG'ed to 2s.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.88 . ERI* = 0.88 . The ERI for only the G78.12+3.63 blocks was 0.875. The losses include Mc's field-system casualty during the first of two blocks.

Plots of the autocorrelations .
Comments.
Two pages of plots for each scan.

Plots of the uncalibrated amplitude and phase against time .
Comments.
full-experiment Ef-* baselines, no calibration applied.

Plots of the uncalibrated amplitude and phase against frequency channel .
Comments.
Two pages of plots for each scan for Ef-* baselines, scalar averaged. Ef-Nt emission shows up very very weakly.

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

TSYS against time .
Comments.
TY1 table. There was no Da or Cm Tsys info because of the data transmission over the micro-wave link -- set to 1.

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 from CL2 table.

Fringe-fit phase solutions (including Parallactic Angle correction).
Comments.
CL3 station phase solutions.

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

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

Telescope bandpasses .
Comments.
bandpass table 1. Only 3C345 and 3C454.3 were used for bandpass calibration.

Calibrated amplitude and phase against time (a priori amplitude calibration and fringe-fit solutions applied).
Comments.
Ef-* baselines calibrated with table CL3.

Calibrated amplitude and phase against frequency channel .
Comments.
One or two pages of plots per source (depending on number of detections remaining in CL3), showing Ef-* baselines calibrated with CL3 and BP1. The edges of the band have been overcompensated somewhat in the bandpass correction process.
