Brief data summary
and
scan listing
)
RO004A was observed on 06 June 2012. It used 10 EVN stations and a setup of 16 x 8 MHz IF. The post correlation (correlated using the software correlator) consisted of 64 frequency points. Here it is the pipelining results. In the pipelining, the SOLINT was set at 1.0 min and Ef, and Ys were used as the reference station. 0528+134 was both fringe-finders and bandpass calibrators. The target source was 0536+145.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.98 (Ef=1, On=1, Ys=1, Jb=1, Mh=1, Nt=1, Sv=1, Zc=0.92, Ur=1, Hh=1) . ERI* = 0.98 .
Plots of the autocorrelations
Comments.
Sv (IF3-LL) and Hh (IF2) show a strong RFI. (possible water maser)
plots of the uncalibrated amplitude and phase
against time
Comments.
Full-experiment on 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. Strong line emission in ORIKL1 (IF1).
The uncalibrated amplitude and phase of the crosshand
correlations against frequency channel
Comments.
Strong line emission (RFI) in IF3 (LL) of the baseline Ef-Sv.
TSYS against time
Comments.
TY1 table.
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. No solutions for Sh and Ur.
Fringe-fit delay solutions
Comments.
SN2 station delay solutions for the fringed sources. Proper solutions found at all stations. No solutions for Sh and Ur.
Fringe-fit rate solutions
Comments.
SN2 station rate solutions. No solutions for Sh and Ur.
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 off-amplitude of Ef-Sv IF3 (LL) is due to the RFI.
