Large Bright Quasar Survey VI (LBQS)
Listed in IVOA Registry (Virtual Observatory)
Positions, redshifts, and magnitudes for the 1055 quasars in the Large Bright Quasar Survey (LBQS) are presented in a single catalog.
Description
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.
