General Comments. ( Brief data summary and scan listing )
N14M1 had 14 stations (including DBBC from Tr, Ys, Mc, T6 which are listed as Td, Yd, Md, and Sd, respectively), 16 x 2 MHz IFs, 4 polarizations, and used 64 frequency points per IF/pol, with 1s integrations. The SOLINT was set at 1.0 min. Ef and Wb were used as the reference stations. The fringe-finder and bandpass calibrator was 'J2202+4216' and 'DA193'. The continuum target source 'J0552+3754' was calibrated using the phase-reference source 'DA193'.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.96 . ERI* = 0.96 . (EF=1, WB=1, JB=0.82, ON=1, MC=1, NT=0.99, TR=1, YS=0.97, SH=1, T6=1, TD=1, YD=0.97, MD=1, SD=1)


Plots of the autocorrelations
Comments.
Each scan plotted separately, all stations. TD, YD, MD and SD are also plotted here. T6: RFI in IF4.


plots of the uncalibrated amplitude and phase against time
Comments.
Full-experiment for Ef-* and Wb-* baselines, no calibration applied.TD, YD, MD and SD are also plotted here.


Plots of the uncalibrated amplitude and phase against frequency channel
Comments.
Scalar averaged Ef-* and Wb-* baselines, each scan plotted separately. No calibration applied yet. TD, YD, MD and SD are also plotted here. T6: RFI in IF4.


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. TD, YD, MD and SD are also plotted here.


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. No solutions for Wb in IF7 and 8; for Sh in IF7 (RR) and IF8.


Fringe-fit delay solutions
Comments.
SN2 station delay solutions for the fringed sources, each IF/pol on a separate plot. No solutions for Wb in IF7 and 8; for Sh in IF7 (RR) and IF8.


Fringe-fit rate solutions
Comments.
SN2 station rate solutions. No solutions for Wb in IF7 and 8; for Sh in IF7 (RR) and IF8.


Telescope bandpasses
Comments.
Bandpass table 1. J2202+4216, and DA193 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-* and Wb-* baselines, calibrated with CL3.


Calibrated amplitude and phase against frequency channel
Comments.
Ef-* and Wb-* baselines calibrated with CL3 and BP1. The amp and phaseplots self-scale, not necessarily going down to 0 in the case of the amps. Maser line visible in IF5.
