VSOP Survey Program observation of J0920+4441

J0920+4441

The data on this page are described in detail in
The VSOP 5 GHz AGN Survey: III. Imaging results for the first 102 sources
by Scott et al. in Astrophysical Journal Supplement, 155, 33-72 (November 2004) .
Please refer to this paper for details of the observations, analysis and interpretation.

The observation of J0920+4441 (0917+449) was made on 07-02-1999 (dd-mm-yyyy)
with HALCA and 4 ground radio-telescopes over a duration of 4:00 (hours:minutes).
Baselines to HALCA were not necessarily available for all of that time.
The survey code for this source is vs07x.
The observation was correlated at the Socorro correlator.
The source is classified as a quasar at a redshift of 2.180.
Please refer to the paper for full details and references.

Specific notes in the above paper for this source are:
This is a complex source. We have assumed the core to be the strong,
compact, central component. There is extended emission on both sides
of this core. The area subtended by the core is < 0.3 mas^2.
