cds-question@unistra.frsurveysquasarsvisible-astronomysloan-photometryredshiftedWe present the final spectroscopic QSO catalogue from the 2dF-SDSS LRG (luminous red galaxy) and QSO (2SLAQ) survey. This is a deep, 18<g<21.85 (extinction corrected), sample aimed at probing in detail the faint end of the broad line active galactic nuclei luminosity distribution at z<=2.6. The candidate QSOs were selected from SDSS photometry and observed spectroscopically with the 2dF spectrograph on the Anglo-Australian Telescope. This sample covers an area of 191.9 deg2 and contains new spectra of 16326 objects, of which 8764 are QSOs and 7623 are newly discovered [the remainder were previously identified by the 2dF QSO Redshift Survey (2QZ) and SDSS]. The full QSO sample (including objects previously observed in the SDSS and 2QZ surveys) contains 12702 QSOs. The new 2SLAQ spectroscopic data set also contains 2343 Galactic stars, including 362 white dwarfs, and 2924 narrow emission-line galaxies with a median redshift of z=0.22.2009MNRAS.392...19Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/392/19CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/241 : The 2dF QSO Redshift Survey (Croom+ 2004)II/294 : The SDSS Photometric Catalog, Release 7 (Adelman-McCarthy+, 2009)J/MNRAS/372/425 : 2dF-SDSS Luminous Red Galaxy Survey, 2SLAQ (Cannon+, 2006)J/MNRAS/381/211 : Radio galaxies in the 2SLAQ LRG Survey (Sadler+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/392/19https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/392/19http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/392/19https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/392/19https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/392/19http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/392/19GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/392/19/2slaqqso (2SLAQ spectroscopic catalogue, built using add_IDs.pl version 1.2 (2008/02/16))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/392/19/2slaqqso?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/392/19/2slaqqso?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/392/19/2slaqqso?GETtext/xml+votable180.050000true123.006485-0.526988890.005555555555555556Cone search capability for table J/MNRAS/392/19/tablea1 (The observed 2dF field centres in the 2SLAQ survey with dates observed)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/392/19/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/392/19/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/392/19/tablea1?GETtext/xml+votable180.050000true123.5-0.209720.0055555555555555565/4351 4435-4438 4441-4442 4451-4454 4457-4458 4495 4499 4501-4502 4505-4506 4516-4518 4521-4522 4687 4693-4694 4696-4698 4708-4710 4713-4714 4757-4758 4761-4762 4772-4774 4776-4778 5455 5461-5462 5465-5466 5784 5786 5795 5797-5798 5800-5802 6463 6479 6484-6486 6501-6502 6505-6506 6543 6549-6550 6554 6565-6566 6719 6756-6758 6761-6762 6805-6806 6809 6822 6824-6826 7508-7510 7849-7850 9215 10239 11263 12287 6/0-2 4096-4098 8192-8194 12288-12290 17659 17661-17663 17723 17725-17727 17739 17756-17758 17761-17763 17772-17774 17776-17778 17803 17820-17822 17825-17827 17836-17838 17840-17842 17856-17858 18001-18003 18012-18014 18017-18019 18028-18030 18032-18034 18061-18063 18076-18078 18081-18083 18092-18094 18096-18098 18112-18114 18176-18178 18683 18685-18687 18763 18765-18767 18769-18771 18780-18782 18796-18798 18800-18802 18823 18827 18829-18831 18844-18846 18849-18851 18860-18862 18864-18866 18880-18882 18999 19003 19005-19007 19019 19021-19023 19025-19027 19036-19038 19041-19043 19052-19054 19056-19058 19079 19083 19085-19087 19100-19102 19116-19118 19120-19122 19136-19138 19200-19202 19456-19458 21837-21839 21841-21843 21852-21854 21857-21859 21868-21870 21872-21874 21909 21952-21954 23095 23099 23101-23103 23142 23148-23150 23185-23187 23196-23198 23212-23214 23216-23218 23232-23234 25847 25851 25927 25933-25935 25948-25950 25956-25957 25959 25962 25968-25970 25991 25995 25997-25999 26001-26003 26012-26014 26017-26019 26028-26030 26032-26034 26048 26050 26183 26189 26191 26193-26195 26204-26206 26210 26224-26225 26253-26255 26257-26259 26268-26270 26277 26288-26290 26304-26306 26368-26370 26939 26942 27019 27021-27023 27036-27038 27041-27043 27052-27054 27056-27058 27074 27213-27215 27217-27219 27228-27230 27233 27248-27250 27271 27277-27279 27281-27283 27286 27292-27294 27308-27310 27312-27314 27392-27394 30023 30029-30031 30044-30046 30053 30064-30065 31371 31374-31375 31393-31395 31404-31406 31410 40951 45051 491439.276497240453405e-25 6.090060298487514e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/392/19?format=asciiOpticaldefaultJ/MNRAS/392/19/2slaqqso2SLAQ spectroscopic catalogue, built using add_IDs.pl version 1.2 (2008/02/16)RunSDSS Run numbermeta.idintzredExtinction in z bandmagphot.color.excessfloatS/G?
