MILLIQUAS 2.9 includes data up to 31 March 2012. 1,184,209 objects are displayed, including 151281 QSOs from the literature (type I only), 20526 AGNe (ie, Seyferts for which the disk outshines the core), 1587 Bl Lacs, 928512 photometric quasars (primarily from SDSS-based NBCKDE and BOSS), and 82303 radio/X-ray associated QSO candidates. A radio and/or X-ray identification is shown where applicable, plus, for the photometric and radio/X-ray associated objects, the probability of each being a true quasar. These expected yields total to 1,059,968 quasars, making MILLIQUAS a true million-quasar catalog.
Here is the ReadMe for the catalog, which gives details, file layout and references for the source data. Appendix A of the ReadMe gives details of the photometric selection and processing.
