General Comments. ( Brief data summary and scan listing )
E025, C-band VLBI experiment on 2016 May 30. EC057A had 10 good stations, 8, 16 MHz IFs, 2 polarizations 32 frequency points per IF/pol, and 1s integrations. Participating telescopes were Jodrell Bank, Westerbork (single dish), Effelsberg, Medicina, Noto, Onsala, Tianma, Torun, Yebes and Irbene Ef was used as reference.


The EVN reliability indicator (ERI) for this experiment was:
(EF=1 JB=1 WB=1 MC=1 NT=0.8 O6=1 T6=1 TR=0.4 YS=1 IR=1) Counting losses: TR antenna control hung between 00:51 and 06:35, Noto no data between 02:42 and 06:37 due to MK5 problem.

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

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 showing LR, each scan plotted separately. No calibration applied yet.

TSYS against time
Comments.
TY1 table, each IF/pol on a separate plot. Note the dropouts for Torun and Noto as explained above (and in the piletter).

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.

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

Telescope bandpasses
Comments.
Bandpass table 1. J2015+3710 was used for bandpass calibration. Not the Noto triangle bandpasses in LCP. Also Torun subband 2 LCP

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.
