2001A&A...374...92V A catalogue of quasars and active nuclei: 10th edition M.-P. Veron-Cetty and P. Veron Observatoire de Haute Provence, CNRS, 04870 Saint-Michel l'Observatoire, France; e-mail: mira@obs-hp.fr Received 11 May 2001/Accepted 13 May 2001 Abstract. The recent publication of the first release of the 2dF quasar catalogue (Croom et al. 2001) containing nearly 10 000 new QSOs, almost doubling the number of known such objects, led us to prepare an updated version of our catalogue of quasars and active nuclei which now contains 23760 quasars, 608 BL Lac objects and 5751 active galaxies (of which 2765 are Seyfert 1s). Like the ninth edition, it includes position and redshift as well as photometry (U, B, V) and 6 and 11 cm flux densities when available. We also give a list of all known lensed and double quasars. Key words: quasars: general - galaxies: Seyfert - BL Lacertae objects: general.
