General Comments.
(
Brief data summary
and
scan listing
)
N15L2 had 13 stations (+ VDif data from Ef and O8 that are listed as Ex and Ox, respectively), 16 x 8 MHz IFs, 4 polarizations, and used 64 frequency points per IF/pol, with 1s integrations. The SOLINT was set at 1.0 min. Ef was used as the reference station. The fringe-finder and bandpass calibrator were 'J0854+2006', 'J0011+0823', 'J0126+2559', '4C39.25', and'0234+285'.
The EVN reliability indicator (ERI) for this experiment was
ERI = 1.00 . ERI* = 1.00 .

Plots of the autocorrelations
Comments.
Each scan plotted separately, all stations. Spme RFIs.
plots of the uncalibrated amplitude and phase
against time
Comments.
Full-experiment for Ef-* baselines, no calibration applied.
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.
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. No antabfs files have been considered for EX, OX, and WD.
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. J0854+2006, J0011+0823, J0126+2559, 4C39.25, and0234+285 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-* 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.
