Abstract:
We present a sample of 1744 type 1 active galactic nuclei (AGNs) from
the Sloan Digital Sky Survey Data Release 4 (SDSS DR4) spectroscopic
catalog with X-ray counterparts in the White-Giommi-Angelini Catalog
(WGACAT) of ROSAT PSPC pointed observations. Of 1744 X-ray sources,
1410 (80.9%) are new AGN identifications. Of 4574 SDSS DR4 AGNs for
which we found radio matches in the catalog of radio sources from the
Faint Images of the Radio Sky at Twenty cm survey, 224 turned up in
our sample of SDSS X-ray AGNs. The sample objects are given in a
catalog that contains optical and X-ray parameters and supporting
data, including redshifts; it also contains radio emission parameters
where available. We illustrate the content of our catalog and its
potential for AGN science by providing statistical relationships for
the catalog data.
