GENERAL
This part of EG031 comprised 8 stations with 1 2MHz IF (DC edge 6667.3MHz)
with 1 polarization (LCP). There were 2048 frequency points, and
integration times were 2s.
Considerably more information is included in the experiment's cover letter
on the standard-plots portion of the EVN Archive. In the pipelining,
only NRAO530 was fringed. A SOLINT of 2.0min was used.
The EVN reliability indicator was ERI=1.0. ERI estimates the ratio of
good -to- expected visibilities. The value of 1 essentially means that there
were no systematic losses due to playback. The On RFI near the middle of
the band that may affect tracing the full line shape on On-* baselines
wasn't explicitly included in this calculation.
///
POSSM_AUTOCORR
21p of plots, one for each scan. RFI and/or internal birdies in On, Tr.
See cover letter for more details.
///
VPLOT_UNCAL
full-experiment Ef-* baselines, no calibration applied.
///
POSSM_UNCAL
21p of plots, on for each scan for Ef-* baselines.
///
TSYS
TY1 table. There was no Da Tsys info because of the data transmission
over the micro-wave link -- set to 1.
///
GAIN
gain from CL2 table.
///
FRING_DELAY
SN2 station delay solutions. Some obvious outliers (On RCP at ~2100).
Evident deviations between residual delay for B1530 & J1613. Noticeable
slope for Ar.
///
FRING_RATE
SN2 station rate solutions (a few obvious outliers that affect automatic
AIPS-determined phase-connection decisions).
///
FRING_PHAS
CL3 station phase solutions. some phase-connections are clearly affected
by RATE outliers (Jb LCP at ~2030).
///
BANDPASS
bandpass table 1. Only NRAO530 was used for bandpass calibration.
///
VPLOT_CAL
Ef-* baselines calibrated with table CL3.
///
POSSM_CAL
297p of plots, showing Ef-* baselines calibrated with CL3 and BP1.
The edges of the band have been apparently overcompensated in the
bandpass correction process.
///
IMAPN
Natural-weighted (dirty) maps for the calibrators B1530, J1613, and J1516
(the latter two having very few scans -- 1 for J1516 leading to a very
elliptical beam indeed)
///
IMAPU
Uniform-weighted (dirty) maps of the above calibrators.
///
CALIB_PHAS1
For each of the calibrators (B1530, J1613, J1516), plots of post-SPLIT
tables SN1. J1516 had only 1 scan.
///
CALIB_AMP2
As above, but for the post-SPLIT table SN2
///
SENS
CL4 gain-amp.
///
CLPHS
For each of the calibrators (B1530, J1613, J1516), 24p of plots
showing closure phase for the triangles (not just Ef-*-*).
///
VPLOT_MODEL
For each of the calibrators, plots of amp/phase on Ef-* baselines
calibrated with (post-SPLIT) table CL3, with a model-line overplotted.
J1516 has only 1 scan, so its time-axis has quite high resolution indeed...
///
UVCOV
For each of the calibrators, a plot of the u-v coverage. (comparing J1516
to the EG031_2 pipeline shows the effect of replacing Cm with Mc on the
'snapshot' u-v coverage)
///
UVPLT
For each of the calibrators, a plot of amp vs. |uv| distance.
///
ICLN
For each of the calibrators, a CLEAN map resulting from the automated
fringing/self-cal pipeline script.
///
