General Comments. ( Brief data summary and scan listing )
N14M3 had 8 stations, 8 x 2 MHz IFs, 4 polarizations, and used 64 frequency points per IF/pol, with 2s integrations. The SOLINT was set at 1.0 min. Ef was used as reference station. The fringe-finder and bandpass calibrator was 'DA193', '3C286', '3C345', '3C273', and 'J0927+3902'. The continuum target source 'J1640+3946' was calibrated using the phase-reference sources '3C345'.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.75 . ERI* = 0.75 . (EF=1, WB=1, JB=1, ON=1, NT=0, TR=1, YS=1, SR=1) - NT disk pack was damaged.


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. here.


Plots of the uncalibrated amplitude and phase against frequency channel
Comments.
Scalar averaged Ef-* baselines, each scan plotted separately. No calibration applied yet. The amplitude of IFs #3 (LL) and #4 (LL) in Ef-Jb is slightly lower than in the other IFs (for all scans).


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


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.


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 phaseplots self-scale, not necessarily going down to 0 in the case of the amps.
