Default Million Quasars catalog now includes SDSS-DR8

The MILLIQUAS (Million Quasars) catalogue v2.3 is now available, it
presents all type I QSOs/AGNe and Bl Lacs up to the release of
SDSS-DR8 in January 2011, including photometric SDSS targets from the
NBCKDE and XDQSO (BOSS) catalogs, and radio / X-ray objects of =70%
likelihood of being quasars.. The count is 1221065 objects which,
using their expectation values, will yield 1083685 actual quasars,
making MILLIQUAS a true million-quasar catalogue. Each object is
shown with an associated radio/X-ray detection where applicable. This
catalogue, ReadMe and sample data are available from:

http://quasars.org/milliquas.htm

and also can be queried on the NASA HEASARC site:
