General Comments. ( Brief data summary and scan listing )
EM111 was observed on 20 February 2014. It used 14 EVN stations and a setup of 8 x 16 MHz IFs. The post correlation consisted of 32 frequency points. Here it is the pipelining results. In the pipelining, the SOLINT was set at 2.0 min and Ef was used as the reference station. 0528+134 and DA193 were both fringe-finders and bandpass calibrators. The target source was J0632+057 that was phase-referenced by using the calibrator J0619+0736.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.80 (Ef=1, Jb=1, On=1, Wb=1, Mc=1, Nt=1, Tr=1, Sv=0, Zc=0.57, Bd=1, Ur=1, Sh=1, Hh=1, Ro=1) . ERI* = 0.80 . Sv no data have been sent (see Experiemtn Feedback).


Plots of the autocorrelations
Comments.
Each scan plotted separately, all stations. Strong RFIs in Jb (RR & LL), Mc (RR), On (RR & LL), Tr (RR & LL), Hh (RR), Zc (RR & LL), Bd (RR & LL), and Ur (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. No fringes for Tr in IF7 (RR) and IF8 (RR)


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. No Tsys for RO (RCP)


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.
