cds-question@unistra.frquasarsredshiftedline-intensitiesspectroscopyultraviolet-astronomyx-ray-sourcesactive-galactic-nucleiWe use UV/optical and X-ray observations of 272 radio-quiet Type 1 active galactic nuclei and quasars to investigate the CIV Baldwin Effect (BEff). The UV/optical spectra are drawn from the Hubble Space Telescope, International Ultraviolet Explorer and Sloan Digital Sky Survey archives. The X-ray spectra are from the Chandra and XMM-Newton archives. We apply correlation and partial-correlation analyses to the equivalent widths (EWs), continuum monochromatic luminosities, and {alpha}_ox_, which characterizes the relative X-ray to UV brightness. The EW of the CIV{lambda}1549 emission line is correlated with both {alpha}_ox_ and luminosity. In our sample, narrow Fe K{alpha} 6.4keV emission lines are detected in 50 objects.2009ApJ...702..767Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/702/767CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/260 : The SDSS-DR7 quasar catalog (Schneider+, 2010)B/hst : HST Archived Exposures Catalog (STScI, 2007)J/ApJ/696/924 : UV and X-Ray radio-quiet QSOs (Gibson+, 2009)J/ApJS/183/17 : The SDSS DR5/XMM-Newton quasar survey (Young+, 2009)J/ApJ/685/773 : X-ray-UV relations in SDSS DR5 QSOs (Gibson+, 2008)J/AJ/133/313 : AGN from RASS and SDSS DR5 (Anderson+, 2007)J/ApJ/657/116 : X-ray and UV parameters of radio-quiet quasars (Kelly+,J/AJ/133/1780 : GALEX/SDSS quasar catalog (Trammell+, 2007)J/ApJ/641/78 : CIV variability in 105 SDSS quasars (Wilhite+, 2006)J/ApJS/166/470 : SDSS-Spitzer type I QSOs IR photometry (Richards+, 2006)J/MNRAS/301/1019 : Seyfert galaxies/radio-quiet QSO correlation (Roy+, 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/702/767https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/702/767http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/702/767https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/702/767https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/702/767http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/702/767GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/702/767/table2 (UV properties of the combined sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/702/767/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/702/767/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/702/767/table2?GETtext/xml+votable180.050000true189.91455-5.34421110.0055555555555555566/1405 2221 4488 4506 4759 4808 5016 5069 5091 5103 5244 5299 5305 5306 5437 5481 5563 5687 5715 5723 5731 5860 5952 5988 6030 6056 6057 6079 6086 6107 6121 6139 6196 6236 6552 6576 6579 6605 6977 7168 7266 7281 7424 7448 7456 7459 7500 7552 7728 7815 7998 8071 8203 8528 8636 8659 8845 8906 8922 8941 9146 9147 9148 9150 9151 9185 9194 9262 9367 9481 9506 9512 9747 9750 9776 9855 9959 10074 10153 10162 10217 10265 10345 10512 10513 10515 10517 10518 10529 10578 10588 10589 10609 10618 10664 10694 10706 10709 10734 10843 10888 10968 10970 10994 11073 11191 11194 11206 11214 11217 11308 11337 11371 11388 11410 11424 11428 11498 11596 11668 11785 11791 11793 11807 11854 11924 11940 12025 12380 15351 16671 17075 17237 17300 17492 17727 17749 17751 17767 17778 17813 17814 17819 18005 18007 18022 18024 18076 18086 18088 18406 18411 18800 18880 19087 19283 19416 19433 19458 19730 19746 19760 19842 19883 19932 19983 22890 25182 25585 25846 25852 25938 25950 25965 25977 25981 26005 26148 26175 26268 26269 26292 26310 26313 26509 26650 26955 26966 27023 27127 27227 27256 27258 27365 27428 27652 27654 27720 27773 27848 27862 27868 27954 28060 28184 28356 28471 28511 29398 31313 31534 31650 32683 33716 33930 34881 35542 36773 36775 36780 36786 38268 39118 44785 44988 45044 47169 49042 49106https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/702/767?format=asciiX-rayUVOpticaldefaultJ/ApJ/702/767/table2UV properties of the combined samplerecnoRecord number assigned by the VizieR team.
