Brief data summary
and
scan listing
)
L band phase-referencing continuum experiment, observed on 17 June 2015. 10 stations participated in the experiment. Below are reported the pipeline results of the correlation pass for J132952+4712. This pass has 8 X 16 MHz subbands, dual polarization, and was correlated by using 64 frequency points per IF/pol, with 2s integrations. Ef was used as the reference station. The fringe-finder and bandpass calibrators were '3C286', '1156+295', and 'OQ208'. The target source 'J132952+4712' was calibrated using the phase-reference source 'J1332+4722'.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.74 . ERI* = 0.81 .
(EF=1, WB=1, JB=1, O8=0.6/1, MC=0.63, TR=0.88, SV=0.88, ZC=1, BD=0.80, SH=1)
Plots of the autocorrelations
Comments.
Each scan plotted separately, all stations. Several 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.
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. OQ208, 3C286, and 1156+295 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 phase plots self-scale, not necessarily going down to 0 in the case of the amps.
