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: http://heasarc.gsfc.nasa.gov/W3Brows...milliquas.html Eric Flesch Wellington, New Zealand |
