General Comments.
(
Brief data summary
and
scan listing
)
EE039 had 11 stations, 8 16MHz IFs, two polarizations, 64 frequency points per IF/pol, and 4s integrations. Considerably more information is included in the experiment's cover letter on the standard-plots portion of the EVN Archive. Ef was used as the reference station.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.786 . ERI* = 0.786 .
The losses include Sv (was out for the central bearing repair), Ar (disk pack was conditioned before correlation) and Mc (had a data throttling problem)
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 0.5 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
(not available)
Comments.
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. For this experiment, one lag corresponds to 1/16 microsecond of delay.
Fringe-fit rate solutions
Comments.
SN2 station rate solutions.
Telescope bandpasses
Comments.
Bandpass table 1. 1156+295, J1333+1649 and OQ208 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 2-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.
