General Comments.
(
Brief data summary
and
scan listing
)
EP088D had 13 good stations, 8 16MHz IFs, 4 polarizations, 32 frequency points per IF/pol, and 1s integrations. Considerably more information is included in the experiment's cover letter on the standard-plots portion of the EVN Archive. This pipelining corresponds to the non-multi-phase-center output for all the targets except NGC6090A,B. 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, and then Ys, were used as the reference stations.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.841 . ERI* = 0.841 .
The losses include no fringes to Nt and Tr having no fringes in IF7-8/RCP.
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. A 1.5 minute plot-averaging was used.
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. Some outliers in individual solints that throw off the automated phase-connection choices (e.g., Jb ~00:50, On ~05:00 in some IF/pol, Zc ~22:00), as reflected in the FRING_PHAS plot.
Telescope bandpasses
Comments.
Bandpass table 1. 3C454.3 and J1824+5651 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. The 1.5-min plot-averaging still applied.
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.
