Of the 1874 objects in the catalogue as published in 1986 (1878 in this version), 1715 comprise a statistically complete sample covering 10714 square degrees from 266 fields taken on the Palomar 18-inch Schmidt telescope. Limiting magnitudes vary from field to field, ranging from 15.49 to 16.67. The overall completeness is estimated to be 84%, but that figure and the relative contributions of magnitude, color, and accidental errors vary depending on the magnitude and color distribution of the spectroscopic subsample. 1986ApJS...61..305G https://cdsarc.cds.unistra.fr/viz-bin/cat/II/207A Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to II/223 : First Byurakan Survey (FBS), 2nd Program (Abrahamian et al., 1996) J/AJ/111/645 : Morphology of Bright Quasars of this list (Fabian+ 1996) J/A+A/250/370 : Far-UV excess object survey (Bixler+ 1991) J/ApJS/156/47 : DA white dwarfs from the Palomar Green Survey (Liebert+, 2005) https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=II/207A https://vizier.iucaa.in/viz-bin/VizieR-2?-source=II/207A http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=II/207A https://vizier.cds.unistra.fr/viz-bin/votable?-source=II/207A https://vizier.iucaa.in/viz-bin/votable?-source=II/207A http://vizieridia.saao.ac.za/viz-bin/votable?-source=II/207A GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table II/207A/catalog (Palomar-Green Survey Data (original catalog completed by accurate positions)) https://vizier.cds.unistra.fr/viz-bin/conesearch/II/207A/catalog? https://vizier.iucaa.in/viz-bin/conesearch/II/207A/catalog? http://vizieridia.saao.ac.za/viz-bin/conesearch/II/207A/catalog?
