General Comments. ( Brief data summary and scan listing )
EP067 observed for 16 hours and had 10 stations;Ef Nt Tr Jb Da On Mc Ur Sh Wb, 16 bands with 8 MHz, dual polarization and 2-bit sampling. 2s integrations were used. In the pipelining, the target sources were treated as phase-referenced sources and not directly fringed. The target sources were WNB1328.3+65, WNB1438.0+37, WNB1408.8+46 and WNB1458.0+49; phase referenced by J1344+6606, J1417+4607, J1440+3820 and J1506+4933 respectively. The SOLINT was set automatically at a representative length of a reference-source scan in a phase-reference cycle. Ef was used as the reference station.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.95 . ERI* = 0.95 . Ef=1, Mc=1, On=1, Jb=1, Tr=1, Da=0.79, Wb=1, Nt=1, Sh=1, Ur=1.


Plots of the autocorrelations
Comments.
Each scan plotted separately, all stations. In general fairly stable bandpasses.RFI spikes in Mc and Jb IF 8.


plots of the uncalibrated amplitude and phase against time
Comments.
Full-experiment for Ef-* baselines, no calibration applied.


Plots of the uncalibrated amplitude and phase against frequency channel
Comments.
Scalar averaged Ef-* baselines, each scan plotted separately. No calibration applied yet.


The uncalibrated amplitude and phase of the crosshand correlations against frequency channel (not available)
Comments.
Scalar averaged Ef-* baselines for LR, each scan plotted separately. No calibration applied yet.


TSYS against time
Comments.
TY1 table, each IF/pol on a separate plot. Some very high Tsys measurements for Jb and Mc IF 7 and 8.


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, each IF/pol on a separate plot. Delays fairly stable.


Fringe-fit rate solutions
Comments.
SN2 station rate solutions.


Telescope bandpasses
Comments.
Bandpass table 1. 3C345, 3C286 and OQ208 were used for bandpass calibration. Phases deviate from center at edges of bandpass.


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 amp and phase plots self-scale, not necessarily going down to 0 in the case of the amps.
