cds-question@unistra.frsurveysquasarsWe present the Bright Quasar Survey (BQS) consisting of 114 objects to an average limiting magnitude B=16.16 over an area of 10714{deg}^2^. There are 92 quasars with M_B_<-23 in the sample. We use the BQS and complete samples from published surveys to derive models of the statistical evolution of quasars. The increase of space density with redshift depends strongly on absolute luminosity, being close to zero for low-luminosity quasars. Detailed predictions are given for the distribution of redshifts and magnitudes and for the total counts based on the evolution models.1983ApJ...269..352Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/269/352CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/108/1163 : Radio structure of Quasars (Kellermann+ 1994)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/269/352https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/269/352http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/269/352https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/269/352https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/269/352http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/269/352GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/269/352/table1 (The Palomar Bright Quasar Survey)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/269/352/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/269/352/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/269/352/table1?GETtext/xml+votable180.050000true1.49649116.1636060.0055555555555555566/2081 4215 4506 5091 5244 5290 5437 5481 5576 5687 5731 5974 6028 7246 7998 8017 8071 8282 8299 8528 8636 8641 8845 8881 8893 8906 8927 8941 8952 9018 9181 9194 9262 9457 9705 9955 9959 10039 10084 10162 10217 10269 10472 10495 10578 10659 10691 10694 10709 10807 10940 11217 11354 11388 11668 11723 11829 11924 12317 12380 12632 17819 18125 18127 18912 18918 19287 19315 19416 19433 19567 19609 19700 19730 19746 19767 19807 19883 19932 25403 25735 25742 25965 26033 26292 26310 26323 26509 26615 26736 26859 26902 27005 27023 27025 27127 27227 27293 27349 27580 27581 27720 27848 27862 27964 28060 28086 28148 28164 28356 28471 31650 44785 44988https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/269/352?format=asciidefaultJ/ApJ/269/352/table1The Palomar Bright Quasar SurveyPGPG numbermeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
