Abstract:
The VSOP mission is a Japanese-led project to image radio sources with
sub-milliarcsec resolution by correlating the signal from the orbiting
8-m telescope, HALCA, with a global array of telescopes. Twenty- five
percent of the scientific time of this mission is devoted to a survey
of 402 bright, small-diameter extra-galactic radio sources at 5-GHz.
The major goals of the VSOP Survey are statistical in nature: to
determine the brightness temperature and approximate structure; to
provide a source list for use with future space VLBI missions; and to
compare radio properties with other data throughout the EM spectrum.
This paper describes: the compilation of a complete list of radio
sources associated with active galactic nuclei (AGN); the selection of
the subsample of sources to be observed with VSOP; the extensive
ground resources used for the Survey; the status of the observations
as of 2000 July; the data-analysis methods; and several examples of
results from the VSOP Survey. More detailed results from the full
sample will be given in future papers.

Note (1): the asterisk indicates that the spectral index or galactic
latitude are outside of the sample specifications (α>-0.45
and |b|>10°) and the source is not formally part of the complete
sample. Some of these sources have S5GHz>5.0Jy (all such sources
were included) and some sources appear to have a spectral index
α←0.45, based on information not available when the
source list was first compiled.
A 'd' was added for the source J1932-4546/J1932-4536 having a
10arcmin error in declination and name (see the "History" section
below).

History:
* 27-Jun-2003: Prepared via OCR at CDS.
* 16-Sep-2009: Declination and JName of source originally named
'J1932-4546' seems to be in error by exactly 10arcmin, the
actual radio source (QSO B1929-457) being at declination
-45:36:37.9; this correction was applied in this electronic
version of the table.
