cds-question@unistra.fractive-galactic-nucleix-ray-sourcesWe present a detailed description of the first direct measurement of the spatial correlation function of X-ray-selected active galactic nuclei (AGNs). This result is based on an X-ray flux-limited sample of 219 AGNs discovered in the contiguous 80.7{deg}^2^ region of the ROSAT North Ecliptic Pole (NEP) Survey (Cat. <J/ApJS/149/29>).2004ApJ...617..192Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/617/192CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/149/29 : ROSAT North Ecliptic Pole Survey (Gioia+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/617/192https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/617/192http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/617/192https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/617/192https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/617/192http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/617/192GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/617/192/table1 (ROSAT NEP AGN Catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/617/192/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/617/192/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/617/192/table1?GETtext/xml+votable180.050000true258.85541762.6594440.0055555555555555564/1002 5/2557 2559 2901 2903 2909 2910 4012 4014 6/10205 10207 10221 10223 10225 10234 10235 11589 11591 11603 11610 11611 11632 11633 11635 11644 11645 11646 11728 15326 15327 15343 15349 15350 15351 15353 15354 15355 15357 15358 15359 16010 16011 16052 16054https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/617/192?format=asciiX-raydefaultJ/ApJ/617/192/table1ROSAT NEP AGN Catalogf_RXFlag on RX (1)charrecnoRecord number assigned by the VizieR team.
