General Comments. ( Brief data summary and scan listing )
X-band experiment, observed on 1 November 2015. ER038 contains 8 x 16MHz bands and 2 x polarisations, each with 32 frequency points. 3C454.3 was used as the fringe-finder
14 stations scheduled.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.84 . ERI* = 0.84 . The ERI* value takes into account that:
- IR has no data.
- WB missed the last scan.
- NT missed the first scan.
- SV recorded scans 1 - 47 in RCP only.
The ERI value also takes into account losses that are outside the station's control, of which there were none for this experiment.

Plots of the autocorrelations
Comments.
Each scan plotted separately, all stations. Some RFI spikes. Looks like UR IF5L is dead.

Plots of the uncalibrated amplitude and phase against time
Comments.
Full-experiment for Ef-* 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-* baselines, each scan plotted separately. No calibration applied yet. UR IF5L is dead... SH IF1L & 2L look low..

The uncalibrated amplitude and phase of the crosshand correlations against frequency channel (not available)
Comments.
NA

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. ZC L & R are diff...

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. 3C454.3 used for bandpass calibration. Some more edge channel flagging may be beneficial.

Calibrated amplitude and phase against time (a priori amplitude calibration and fringe-fit solutions applied).
Comments.
Full-experiment for Ef-* baselines, calibrated with CL3. A 1.5 minute plot-averaging was used.

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.

As above, but for the post-SPLIT table SN2.

Telescope sensitivities (the total AMP gain applied during both a priori and self calibration; the square of this number gives the antenna noise (SEFD) in Jy).

Comments.
For each source, a plot of the u-v coverage. Some targets have higher amplitudes on longer baselines, which is impossible, suggestion calibration should be improved.
