General Comments. ( Brief data summary and scan listing )
RSC04. L band e-EVN phase-referencing experiment, observed on 23 January 2019. The data rate was 1024 Mbps (8 x 16 MHz subbands, dual polarization, two-bit sampling). The target sources J1821+2633 and J1821+2635 were calibrated using the phase-reference source J1827+2638. The target sources J2052+4723A, J2052+4723B and J2053+4727 were calibrated using the phase-reference source J2102+4702. The target sources J2337+4830 and J2337+4825 were calibrated using the phase-reference source J2325+4806. J1801+4404 and J2236+2828 were observed as the calibrators and the fringe finders.
10 stations participated.

The EVN reliability indicator (ERI) for this experiment was ERI = . ERI* = .

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. A 1.0 minute plot-averaging was used.

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
Comments.

TSYS against time
Comments.
TY1 table, each IF/pol on a separate plot.

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. J1801+4404 and J2236+2828 were used for bandpass calibration.

Calibrated amplitude and phase against time (a priori amplitude calibration and fringe-fit solutions applied).
Comments.
Full-experiment for Ef-** baselines, calibrated with CL3. The 1.0-min plot-averaging still applied.

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.
