cds-question@unistra.frquasarsultraviolet-photometryvisible-astronomyWide-band photometryx-ray-sourcessloan-photometryactive-galactic-nucleiWe have compiled a catalog of optically selected quasars with simultaneous observations in UV/optical and X-ray bands by the Swift Gamma-ray Burst Explorer. Objects in this catalog are identified by matching the Swift pointings with the Sloan Digital Sky Survey Data Release 5 quasar catalog. The final catalog contains 843 objects, among which 637 have both Ultraviolet Optical Telescope (UVOT) and X-Ray Telescope (XRT) observations and 354 of which are detected by both instruments. The overall X-ray detection rate is ~60% which rises to ~85% among sources with at least 10ks of XRT exposure time. We construct the time-averaged spectral energy distribution (SED) for each of the 354 quasars using UVOT photometric measurements and XRT spectra. From model fits to these SEDs, we find that the big blue bump contributes about ~0.3 dex to the quasar luminosity. We re-visit the {alpha}_ox_-L_2500_{AA} relation by selecting a clean sample with only Type 1 radio-quiet quasars; the dispersion of this relation is reduced by at least 15% compared with studies that use non-simultaneous UV/optical and X-ray data.2012ApJS..201...10Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/201/10CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/260 : The SDSS-DR7 quasar catalog (Schneider+, 2010)J/ApJ/728/23 : GALEX UV-bright high-redshift quasars (Worseck+, 2011)J/ApJ/726/20 : X-ray emission from quasars (Miller+, 2011)J/A+A/520/A47 : Blazars in the Swift-BAT hard X-ray sky (Maselli+, 2010)J/AJ/140/1987 : SDSS-GALEX QSO catalog (Hutchings+, 2010)J/ApJ/699/603 : Evolution of Swift/BAT blazars (Ajello+, 2009)J/AJ/137/3761 : Ultraviolet quasi-stellar objects (Bianchi+, 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/MNRAS/382/412 : SDSS-DR5/2MASS spectroscopic quasars (Ofek, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/201/10https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/201/10http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/201/10https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/201/10https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/201/10http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/201/10GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/201/10/table8 (SDSS quasar catalog with Swift observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/201/10/table8?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/201/10/table8?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/201/10/table8?GETtext/xml+votable180.050000true176.259316959.9555650.0055555555555555565/4438 6/4109 4116 4121 4122 4135 4150 4174 4178 4181 4188 4189 4197 4260 4733 4748 4805 4807 4820 4850 4918 4940 4955 4966 4992 4999 5024 5061 5072 5119 5312 5353 5355 5423 5448 5455 5483 5493 5507 5510 5513 5526 5529 5546 5558 5569 5595 5610 5618 5627 5629 5633 5693 5701 5717 5723 5726 5746 5748 5752 5766 5767 5773 5780 5781 5782 5797 5798 5799 5801 5815 5817 5828 5848 5858 5951 5975 5981 6009 6018 6025 6028 6030 6033 6035 6044 6046 6048 6052 6098 6099 6102 6110 6167 6173 6220 6243 6252 6253 6256 6258 6260 6261 6340 6342 6343 6399 6404 6423 6448 6457 6466 6468 6503 6506 6507 6511 6519 6529 6597 6612 6621 6623 6628 6641 6642 6646 6647 6648 7169 7172 7184 7195 7199 7216 7228 7237 7238 7240 7241 7258 7290 7291 7307 7316 7361 7428 7439 7444 7448 7449 7457 7460 7484 7498 7511 7512 7515 7552 8203 8375 8717 8719 9063 9068 9182 9272 9273 9287 9308 9311 9322 9329 9330 9331 9333 9335 9336 9347 9375 9381 9391 9395 9397 9439 9442 9448 9460 9468 9470 9481 9482 9504 9506 9512 9612 9613 9632 9633 9807 9872 9873 9883 9894 9909 9935 9945 9946 9981 9996 10022 10027 10146 10181 10306 10312 10337 10483 10548 10560 10572 10574 10577 10594 10604 10613 10666 10679 10682 10691 10694 10732 10807 10843 10911 10912 10950 10976 10984 11012 11018 11027 11033 11038 11060 11071 11084 11087 11088 11090 11104 11105 11109 11201 11204 11231 11236 11243 11246 11253 11267 11307 11317 11319 11321 11324 11338 11360 11362 11371 11392 11400 11402 11407 11417 11430 11434 11435 11447 11456 11457 11464 11482 11490 11591 11596 11597 11778 11779 11809 11825 11827 11842 11905 11909 11914 11920 11941 12288 12290 12560 17239 17253 17492 17503 17508 17520 17522 17561 17563 17582 17665 17748 17749 17814 17815 17822 17832 17857 18010 18011 18066 18067 18070 18071 18075 18083 18085 18087 18096 18097 18098 18390 18516 18533 18535 18590 18591 18601 18624 18794 18795 18854 19101 19106 19115 19327 19405 19407 19408 19410 19414 19416 19418 19673 19731 21854 21972 23101 23102 23103 23138 23144 23145 23204 23205 25582 25596 25597 25839 25847 25850 25952 25960 25994 26016 26041 26072 26074 26083 26159 26175 26191 26198 26221 26233 26238 26244 26246 26247 26287 26292 26294 26300 26323 26327 26333 26369 26371 26372 26374 26375 26395 26406 26486 26489 26491 26494 26551 26604 26605 26966 26995 27078 27079 27097 27099 27100 27223 27225 27248 27251 27285 27302 27303 27315 27320 27338 27339 27341 27348 27350 27371 27417 27423 27425 27428 27464 27498 27514 27515 27524 27582 27658 27674 27719 27722 27735 27751 27762 27765 27772 27773 27815 27841 27860 27862 27863 27872 27906 27907 27911 27918 27922 27936 27951 27976 28172 28174 28184 28185 28517 28538 28539 28583 28589 28609 28628 28630 28635 28638 28639 28651 28658 28661 28663 28669 30029 31309 31331 31346 31373 31401 31430 31431 31441 31451 32509 36765 36784 36785 36786 36809 36812 36863https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/201/10?format=asciiX-rayUVOpticaldefaultJ/ApJS/201/10/table8SDSS quasar catalog with Swift observationsrecnoRecord number assigned by the VizieR team.
