1993ApJS...87..451H A REVISED AND UPDATED CATALOG OF QUASI-STELLAR OBJECTS A. HEWITT Center for Astrophysics and Space Sciences, University of California, San Diego, La Jolla, CA 92093-0111 AND G. BURBIDGE Center for Astrophysics and Space Sciences, and Department of Physics, University of California, San Diego, La Jolla, CA 92093-0111 Received 1992 November 17; accepted 1993 January 6 ABSTRACT The paper contains a catalog of all known quasi-stellar objects (QSOs) with measured emission redshifts, and BL Lac objects, complete to 1992 December 31. The catalog contains 7315 objects, nearly all QSOs including about 90 BL Lac objects. The catalog and references contain extensive information on names, positions, magnitudes, colors, emission-line redshifts, absorption, variability, polarization, and X-ray, radio, and infrared data. A key in the form of subsidiary tables enables the reader to relate the name of a given object to its coordinate name, which is used throughout the compilation. Plots of the Hubble diagram, the apparent magnitude distribution, the emission redshift distribution, and the distribution of the QSOs on the sky are also given. Subject headings: catalogs - quasars: general
