Abstract:
The VLBI Space Observatory Programme (VSOP) mission is a Japanese-led
project to study radio sources with submilliarcsecond angular
resolution, using an orbiting 8m telescope on board the satellite
HALCA with a global Earth-based array of telescopes. A major program
is the 5GHz VSOP Survey Program, which we supplement here with Very
Long Baseline Array observations to produce a complete and flux
density-limited sample. Using statistical methods of analysis of the
observed visibility amplitude versus projected (u, v) spacing, we have
determined the angular size and brightness temperature distribution of
bright radio emission from active galactic nuclei.

Note (1): Redshift and identification for J1501-3918 and J1658-0739 from
I.A.G. Snellin & P.G. Edwards (2004, private communication);
redshift for J1522-2730 from Heidt et al. (2004A&A...418..813H 2004A&A...418..813H).
Note (2): Optical identification, defined as follows:
q = quasar;
e = elliptical galaxy;
g = faint galaxy (>24mag);
b = BL Lac object;
e = empty field.
Note (3): Status of the survey observation, defined as follows:
A = AGN sample and observed with VSOP;
B = AGN sample, but not yet observed with VSOP or reduced;
C = AGN sample, but too faint to be observed with VSOP;
D = Removed from AGN sample.
