General Comments. ( Brief data summary and scan listing )
N11C3 observed on 20 October, 2011 and had 13 stations: Zc Ef Mc On Jb Ur Tr Ys Sv Hh Wb Sh Bd, 16 x 8 MHz IFs, 4 polarizations, and used 16 frequency points per IF/pol, with 2s integrations. The SOLINT was set at 2.0 min. Ef was used as the reference station. The NME consists of long integrations on J1800+3848 and a phase referencing part with 3C345 and NRAO512 (both strong sources).

The EVN reliability indicator (ERI) for this experiment was ERI = 1.0 . ERI* = 0.89 (no Onsala for 2 hours due to wind) .

Plots of the autocorrelations
Comments.
Each scan plotted separately, all stations.RFI: Ys IF1, Sv IF 6 and 8, Zc IF 3 and 4, Bd IF 7

plots of the uncalibrated amplitude and phase against time
Comments.
Full-experiment for Wb-* baselines, no calibration applied. A 2-minute plot-averaging was used.

Plots of the uncalibrated amplitude and phase against frequency channel
Comments.
Scalar averaged Wb-* 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.
FRING_PHAS 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. Bd: Clock Jump 14:03-14:07, 14:08-14:13

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. The 2-min plot-averaging still applied. Noisy phases for Jb.

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. Jb LL amps lower in IF 3 and 4, Mc LL IF 7 and 8, Ur RR IF 1 and 2, Sv RR IF 2.
