Brief data summary
and
scan listing
)
EE008B_2 was a water maser experiment at 22-GHz on 09 November 2011. It used 9 EVN stations and a setup of 1 x 8 MHz IF. The post correlation (correlated using the software correlator) consisted of 8192 frequency points. 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, 3C286 were both fringe-finders and bandpass calibrators. The target source was ORIKL1 and the phase-referencing source was J0541-0541.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.78 (Ef=1, Jb=1, On=1, Zc=1, Ys=1, Sv=1, Ur=0, Hh=1, Mh=1) . ERI* = 1.00 .
Plots of the autocorrelations
Comments.
Strong RFI: Sv (RR,LL), Zc (LL), Hh (RR). Water masers was detected to all station but Zc (LL).
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. Weak fringes to Hh and Zc.
Plots of the uncalibrated amplitude and phase
against frequency channel
Comments.
Scalar averaged Ef-* baselines, each scan plotted separately. No calibration applied yet. Maser emission in all the baselines.
The uncalibrated amplitude and phase of the crosshand
correlations against frequency channel
Comments.
Maser emission in all baselines.
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 Ys.
Fringe-fit delay solutions
Comments.
SN2 station delay solutions for the fringed sources. Proper solutions found at all stations. No solutions for Ys.
Fringe-fit rate solutions
Comments.
SN2 station rate solutions. No solutions for Ys.
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. Water maser emission in all the displayed baselines. Few baselines for ORIKL1 are showed because of bad fringe solutions from the phase-referencing calibrator. Users should better calibrate it.
