VSOP Survey Program observation of J1146-2447

J1146-2447

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 J1146-2447 (1143-245) was made on 26-05-1999 (dd-mm-yyyy)
with HALCA and 3 ground radio-telescopes over a duration of 7:45 (hours:minutes).
Baselines to HALCA were not necessarily available for all of that time.
The survey code for this source is vs06w.
The observation was correlated at the Mitaka correlator.
The source is classified as a quasar at a redshift of 1.940.
Please refer to the paper for full details and references.

Specific notes in the above paper for this source are:
This is a GPS source (Stanghellini et al. 1997, Astron. Astroph,
325,943). The secondary component to the south coincides with the
extended emission seen in the VLBApls (Fomalont et al. 2000, ApJSupp,
131, 95) and 8 GHz USNO images.
