(
Brief data summary
and
scan listing
)
The S/X band NME experiment N12SX1 was performed on 25 May 2012. The experiment used 11 stations with a recording data rate of 512 Mbps (16 x 8 MHz, 2bit sampling, RCP only). S and X band data were in IF 1-8 and IF 9-16 X respectively. Ys was used as the reference station in the pipelining data reduction.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.6 . ERI* = 0.6 .
(Ef=0.9, Wb=0, Mc=1, On=1, Hh=1, Ys=1, Nt=0, Ur=1, Sv=1, Zc=1, Bd=1).
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. Same clock model was used at both S and X band. At S band, the delay is a bit of larger.
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.
FRING_PHAS 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.
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.

As above, but for the post-SPLIT table SN2.
