General Comments. ( Brief data summary and scan listing )
N12M2_1 had 8 stations, 1 x 8 MHz IFs, 4 polarizations, and used 2048 frequency points per IF/pol, with 1s integrations (only from scan 27). The SOLINT was set at 1.0 min. Ef was used as the reference station. The fringe-finders and bandpass calibrator was'3C345'. The target source 'G35.02' was calibrated using the phase-reference source 'J1856+0610'.

The EVN reliability indicator (ERI) for this experiment was ERI = 1 . ERI* = 1 . (EF=1, WB=1, JB=1, ON=1, MC=1, NT=1, TR=1, YS=1)


Plots of the autocorrelations
Comments.
Each scan plotted separately, all stations. RFI in EF (LL, RR), TR (LL, RR), and YS (LL, RR).


plots of the uncalibrated amplitude and phase against time
Comments.
Full-experiment for Ef-* baselines, no calibration applied. No Fringes in all baselines JB-xx.


Plots of the uncalibrated amplitude and phase against frequency channel
Comments.
Scalar averaged Ef-* baselines, each scan plotted separately. No calibration applied yet. The methanol maser G35.02 is in all the baseline but XX-JB.


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. No solutions for Jb.


Fringe-fit delay solutions
Comments.
SN2 station delay solutions for the fringed sources, each IF/pol on a separate plot. No solutions for Jb.


Fringe-fit rate solutions
Comments.
SN2 station rate solutions. No solutions for Jb.


Telescope bandpasses
Comments.
Bandpass table 1. J1751+0939 and J1748+0832 were used for bandpass calibration. No solutions for Jb.


Calibrated amplitude and phase against time (a priori amplitude calibration and fringe-fit solutions applied).
Comments.
Full-experiment for Ef-* baselines, calibrated with CL3. No JB in the plot.


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. Methanol masers in all the baselines.
