General Comments.
(
Brief data summary
and
scan listing
)
EG046 had 8 stations, 8 16 MHz IFs, two polarizations, and used 16 frequency points per IF/pol, with 2s integrations. In the pipelining, the target sources were treated as phase-referenced sources and not directly fringed. The SOLINT was set automatically at a representative length of a reference-source scan in a phase-reference cycle. Ef was used as the reference stations.
The EVN reliability indicator (ERI) for this experiment was
ERI = 1.0 . ERI* = 1.0 .
Plots of the autocorrelations
Comments.
Each scan plotted separately, all stations.
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
(not available)
Comments.
Scalar averaged Ef-* baselines for 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. 2200+420 and 2251+158 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.

For each source, a CLEAN map resulting from the automated fringing and self-cal iterations (or phase-referencing) in the pipeline script.
