General Comments. ( Brief data summary and scan listing )
N18L3, L band NME on 2018 Nov 1.
The data rate was 512 Mbps (8 x 8 MHz subbands, full polarization, two-bit sampling). J1848+3219 and J2139+1423 were observed as fringe finders.
18 stations participated: Jb2, Wb, Ef, Mc, O8, T6, Ur, Tr, Sv, Zc, Bd, Hh, Sr, Cm, Da, Kn, Pi, De

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 1.5 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.

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. J1848+3219 and J2139+1423 were used for bandpass calibration.

Calibrated amplitude and phase against time (not available) (a priori amplitude calibration and fringe-fit solutions applied).
Comments.
Full-experiment for Ef-** baselines, calibrated with CL3. The 1.5-min plot-averaging still applied.

Calibrated amplitude and phase against frequency channel (not available)
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.

Comments.
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.
CL4 gain-amp.

J1848+3219 (not available) .
J2139+1423 (not available) .
Comments.
