(
Brief data summary
and
scan listing
)
N12M2_1 had 8 stations, 16 x 8 MHz IFs, 4 polarizations, and used 32 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-finders and bandpass calibrators were '3C286' and '3C345'. The target sources 'J1329+3154' and 'G35.02' were calibrated using the phase-reference sources '3C286' and 'J1856+0610'.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.99 . ERI* = 0.99 .
(EF=1, WB=1, JB=0.99, ON=1, MC=1, NT=1, TR=1, YS=1)
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. 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 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.
