General Comments.
(
Brief data summary
and
scan listing
)
RP006 had 6 stations, 4 8MHz IFs, and four polarizations. There were 16 frequency points per IF/pol, and integration times were 1s. More information is included in the experiment's cover letter on the standard-plots portion of the EVN Archive. In the pipelining, IGR1730 and IGR1840 were not fringed individually, since they were targets in phase-referencing pairs. The SOLINT was 80-90 seconds (representative length of a reference-source scan in a phase-ref cycle). Wb was used as the reference station, with Tr as a second reference station.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.643 . ERI* = 0.643 .
The ERI was 0.643. The losses include: ~17% of the time due to global outages (restarting jobs, correlator processes, etc.), ~14% of Mc time (see cover letter), and 50% of the data from Cm (only the LCP seems to show fringes -- see cover letter).
Plots of the autocorrelations
Comments.
Each scan plotted separately, all stations.
plots of the uncalibrated amplitude and phase
against time
Comments.
Full-experiment for Wb-* baselines, no calibration applied. A 1 minute plot-averaging was used.
Plots of the uncalibrated amplitude and phase
against frequency channel
Comments.
Scalar averaged Wb-* baselines, each scan plotted separately. No calibration applied yet.
The uncalibrated amplitude and phase of the crosshand
correlations against frequency channel
Comments.
Scalar averaged Wb-* baselines for the polarization product LR.
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.
2 pages, bandpass table 1. J1743-0350 was used for bandpass calibration.
Calibrated amplitude and phase against time
(a
priori amplitude calibration and fringe-fit solutions applied).
Comments.
Full-experiment for Wb-* baselines, calibrated with CL3. The 1-min plot-averaging still applied.
Calibrated amplitude and phase against frequency
channel
Comments.
Wb-* 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.
