Brief data summary
and
scan listing
)
RE003A was a ToO experiment at 1.6-GHz (OH maser) on 04 November 2011. It used 8 EVN stations and a setup of 3 x 2 MHz IF and 2 bit sampling. The post correlation was one with 2048 frequency points by using the software correlator. Here it is the pipelining results. In the pipelining, the SOLINT was set at 1.0 min and Ef was used as the reference station. 3C84 and 3C286 were both fringe-finders and 3C84 was also bandpass calibrator. The target maser source was OCETI and the phase-referencing source was J0217-0121.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.95 (Ef=0.95, Jb=1, On=1, Mc=1, Tr=1, Wb=1, Ur=1, Hh=1) . ERI* = 0.95 .
Plots of the autocorrelations
Comments.
Strong RFI in: IF1 at Mc,Tr, Ur, Hh; IF2 at Jb, Mc, Tr, Ur, Hh; IF3 at On, Ur;
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. No LCP Fringe to Tr in IF1.
Plots of the uncalibrated amplitude and phase
against frequency channel
Comments.
Scalar averaged Ef-* baselines, each scan plotted separately. No calibration applied yet. Maser line was detected on all the baselines except on Ef-Hh and Ef-Ur. The maser line was detected only in IF2.
The uncalibrated amplitude and phase of the crosshand
correlations against frequency channel
Comments.
Maser lines were detected on all baselines except on Ef-Ur and Ef-Hh.
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.
Fringe-fit delay solutions
Comments.
SN2 station delay solutions for the fringed sources. Proper solutions found at all stations.
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. Maser line on all baselines except on Ef-On, Ef-Ur, and Ef-Hh.
