VSOP Survey Program observation of J0042+2320

J0042+2320

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 J0042+2320 (0039+230) was made on 12-08-1999 (dd-mm-yyyy)
with HALCA and 2 ground radio-telescopes over a duration of 2:30 (hours:minutes).
Baselines to HALCA were not necessarily available for all of that time.
The survey code for this source is vs07u.
The observation was correlated at the Penticton correlator.
The source is classified as a empty field at a redshift of ......

Specific notes in the above paper for this source are:
The VSOP image contains much less flux density than that in the
VLBApls (Fomalont et al. 2000, ApJSupp, 131, 95) and USNO. It may be
variable. The USNO 8.6 GHz image shows an extension 3 mas to the
north-northeast, and an elongation of the core to the south. The
VLBA2cm2 image has an additional component to the south. The VLBApls
(Fomalont et al. 2000, ApJSupp, 131, 95) image, however, shows an
extension to the east.
