General Comments. ( Brief data summary and scan listing )
EL050C was an EVN experiment of faint BL LACs objects at 3.6 cm on 02 June 2015. It used 10 EVN stations and a setup of 8 x 16 MHz IFs, dual polarization, and 2 bit sampling (1Gb/s). In the pipelining, the SOLINT was set at 2.0 min and Ef and Ys were used as the reference station. 3C345 and J0927+3902 were both fringe-finders and bandpass calibrators. The target sources were 1257+2412, 1427+3908, 1012+3932, and 1022+5124 that were phase-referenced by using the calibrators J1312+2531, J1419+3821, J1023+3948, and J1035+5040, respectively.

The EVN reliability indicator (ERI) for this experiment was ERI = (Ef=0.13, Wb=1, O6=1, Mc=1, Nt=1, Sv=1, Zc=0.97, Bd=1, Ys=0.98, T6=0) 0.64 . ERI* = (Ef=1, Wb=1, O6=1, Mc=1, Nt=1, Sv=1, Zc=0.97, Bd=1, Ys=0.98, T6=0) 0.79 .

Plots of the autocorrelations
Comments.
Each scan plotted separately, all stations.

plots of the uncalibrated amplitude and phase against time
Comments.
Full-experiment on Ef-* and Ys-* baselines, no calibration applied. A 1.5-minute plot-averaging was used.

Plots of the uncalibrated amplitude and phase against frequency channel
Comments.
Scalar averaged Ef-* and Ys-* baselines, each scan plotted separately. No calibration applied yet. No fringes to NT LL as expected since they observed only RCP.

The uncalibrated amplitude and phase of the crosshand correlations against frequency channel
Comments.
Scalar averaged Ef-* and Ys-* baselines for LR, each scan plotted separately. No calibration applied yet.

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.

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-* and Ys-* baselines, calibrated with CL3.

Calibrated amplitude and phase against frequency channel
Comments.
Ef-* and Ys-* baselines calibrated with CL3 and BP1.
