cds-question@unistra.frquasarsx-ray-sourcesIn this work we use a sample of 318 radio-quiet quasars (RQQs) to investigate the dependence of the ratio of optical/UV flux to X-ray flux, {alpha}_ox_, and the X-ray photon index, {Gamma}_X_, on black hole mass, UV relative to Eddington luminosity, and X-ray relative to Eddington luminosity. Our sample is drawn from the literature, with X-ray data from ROSAT and Chandra, and optical data mostly from the SDSS; 153 of these sources have estimates of {Gamma}_X_ from Chandra. We estimate M_BH_ using standard estimates derived from the H{beta}, MgII, and CIV broad emission lines. To date, this is the largest study of the dependence of RQQ X-ray parameters on black hole mass and related quantities, and the first to attempt to correct for the large statistical uncertainty in the broad-line mass estimates.2008ApJS..176..355Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/176/355CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/252 : SDSS-DR5 quasar catalog (Schneider+, 2007)J/ApJS/165/1 : BAL QSOs from SDSS DR3 (Trump+, 2006)J/AJ/130/387 : SDSS-ROSAT AGN data (Strateva+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/176/355https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/176/355http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/176/355https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/176/355https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/176/355http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/176/355GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/176/355/table1 (Black Hole Parameters of the Sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/176/355/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/176/355/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/176/355/table1?GETtext/xml+votable180.050000true0.6279170.8330560.0055555555555555566/0 592 2247 4125 4169 4790 5090 5102 5103 5563 5731 5804 5806 5843 5860 5881 5925 5930 5985 5995 6030 6038 6047 6050 6052 6056 6057 6069 6071 6073 6075 6079 6090 6107 6112 6121 6139 6340 6427 6532 6552 6554 6604 6605 7178 7242 7261 7273 7280 7281 7424 7448 7459 7464 7552 9163 9443 9481 9506 9512 9632 9642 9885 9959 9997 10072 10193 10217 10222 10473 10589 10601 10694 10706 10743 10911 11206 11252 11299 11353 11371 11372 11375 11457 11461 11587 11596 11793 11807 17300 17492 17497 17735 17749 17751 17754 17767 17778 17815 17819 17829 17840 17895 18005 18009 18022 18024 18032 18075 18076 18089 18096 18200 18411 18466 18537 18546 18780 18800 19052 19053 19457 19458 19740 19983 23201 25585 25597 25846 25852 25938 25948 25950 25956 25977 25981 26005 26022 26175 26189 26203 26204 26209 26221 26266 26268 26269 26276 26277 26281 26285 26292 26295 26298 26302 26313 26316 26338 26846 26955 26977 26995 27048 27053 27224 27428 27440 27476 27530 27552 27652 27654 27668 27714 27760 31310 32500 32502 33269 36217 36271 36779 36780 36785 36792https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/176/355?format=asciiX-raydefaultJ/ApJS/176/355/table1Black Hole Parameters of the SamplerecnoRecord number assigned by the VizieR team.
