General Comments. ( Brief data summary and scan listing )
This part of EG031 comprised 8 stations with 1 2MHz IF (DC edge 6667.3MHz) with 1 polarization (RCP). 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.


Plots of the autocorrelations .
Comments.
21p of plots, one for each scan. RFI and/or internal birdies in On, Tr. See cover letter for more details.


Plots of the uncalibrated amplitude and phase against time .
Comments.
full-experiment Ef-* baselines, no calibration applied.


Plots of the uncalibrated amplitude and phase against frequency channel .
Comments.
21p of plots, on for each scan for Ef-* baselines.


The uncalibrated amplitude and phase of the crosshand correlations against frequency channel (not available) .
Comments.


TSYS against time .
Comments.
TY1 table. There was no Da Tsys info because of the data transmission over the micro-wave link -- set to 1.


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 from CL2 table.


Fringe-fit phase solutions (including Parallactic Angle correction).
Comments.
CL3 station phase solutions.


Fringe-fit delay solutions .
Comments.
SN2 station delay solutions for NRAO530.


Fringe-fit rate solutions .
Comments.
SN2 station rate solutions for NRAO530.


Telescope bandpasses .
Comments.
bandpass table 1. Only NRAO530 was used for bandpass calibration.


Calibrated amplitude and phase against time (a priori amplitude calibration and fringe-fit solutions applied).
Comments.
Ef-* baselines calibrated with table CL3.


Calibrated amplitude and phase against frequency channel .
Comments.
21p of plots, showing Ef-* baselines calibrated with CL3 and BP1. The edges of the band have been apparently overcompensated in the bandpass correction process, especially on the high end (more visible for NRAO530 since it's amplitude scale isn't dominated by the strong emission line).

NRAO530: postscript , or FITS .

Comments.
Natural-weighted (dirty) maps for the sources.


Uniformly weighted dirty map produced before self-cal of:

9.62+0.2: postscript , or text file .

NRAO530 .
9.62+0.2 .
Comments.
