General Comments. ( Brief data summary and scan listing )
EE008B_1 was a water maser experiment at 22-GHz on 09 November 2011. It used 9 EVN stations and a setup of 2 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 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.
Ur:Strong RFI in IF1. Ef, On, Mh, Ys, Sv, Hh: show a strong line emission in ORIKL1 IF1 (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. No fringes to Ur in IF1 and IF 2. Weak fringes to Hh and Zc in IF1 and IF2.


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 in ORIKL1 (IF1).


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 and Ur.


Fringe-fit delay solutions
Comments.
SN2 station delay solutions for the fringed sources. Proper solutions found at all stations. No solutions for Ys and Ur.


Fringe-fit rate solutions
Comments.
SN2 station rate solutions. No solutions for Ys 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. Strong line emission in ORIKL1 (IF1).Few baselines for ORIKL1 are showed because of bad fringe solutions from the phase-referencing calibrator. Users should better calibrate the fringes.
