General Comments. ( Brief data summary and scan listing )
EE008A was a water maser experiment at 22-GHz on 7 September 2011. It used 6 EVN stations and a setup of 1 x 4 MHz IF, with 4 polarizations and 4096 frequency points per IF/pol. Here are the pipelining results. In the pipelining, the SOLINT was set at 1 min and Ef was used as the reference station. The target maser source ORIKL1 was treated as a phase-referenced source and not directly fringed. The phase-reference source used was J0541+0541.

The EVN reliability indicator (ERI) for this experiment was ERI = (Ef=1, Jb=1, On=1, Ys=1, Sv=1, Zc=1) 1 . ERI* = 1 .

Plots of the autocorrelations
Comments.

plots of the uncalibrated amplitude and phase against time
Comments.
Full-experiment on Ys-* baselines, no calibration applied. A 1-minute plot-averaging was used.

Plots of the uncalibrated amplitude and phase against frequency channel
Comments.
Scalar averaged Ys-* baselines, each scan plotted separately. No calibration applied yet. Maser lines were detected on all the baselines.

The uncalibrated amplitude and phase of the crosshand correlations against frequency channel
Comments.

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 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. 3C84 and J0423-0120 were used for bandpass calibration.

Calibrated amplitude and phase against time (a priori amplitude calibration and fringe-fit solutions applied).
