Description (Abstract of paper):
Positions, redshifts, and magnitudes for the 1055 quasars in the Large
Bright Quasar Survey (LBQS) are presented in a single catalog.
Celestial positions have been rederived using the PPM catalog to
provide an improved reference frame. J2000.0 coordinates are given
together with improved B1950.0 positions. Redshifts calculated via
cross correlation with a high signal-to-noise ratio composite quasar
spectrum are included and the small number of typographic and redshift
misidentifications in the discovery papers are corrected.
Compared to the discovery papers (references below), quasars fainter
than the limit have been deleted, 12 quasars have been added, 10
redshifts have been corrected, and 13 designations (LBQS names) have
been corrected.
