VII/158 A REVISED AND UPDATED CATALOG OF QUASI-STELLAR OBJECTS
================================================================================

History
The files have been copied from the cass157.ucsd.edu (132.239.146.157)
anonymous account on August 31, 1993. A standardization of the files
and their description was performed at CDS to allow automatic conversions
to FITS tables.
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.
