The Million Quasars (Milliquas) catalog, v5.2,  7 August 2017

Note: This catalog of quasars and quasar candidates includes SDSS-DR14 and DR14Q.  This version will be the last one for some time. 

 

MILLIQUAS v5.2 includes quasars from the literature to 5 August 2017, including SDSS-DR14 and SDSS-DR14Q (the visual QSO catalog). 

This edition includes about 607K type-I QSOs & AGNs plus about 1.35 million quasar candidates of 80%+ QSO-likelihood -- exact counts and details are in the ReadMe. Radio and/or X-ray identifications are shown where applicable, plus, for the candidates, the probability of each being a true quasar.

Here is the ReadMe, and a quick browse of sample data (in flat text form) is here.
