cds-question@unistra.fractive-galactic-nucleiquasarsAlthough the variability in the ultraviolet and optical domain is one of the major characteristics of quasars, the dominant underlying mechanisms are still poorly understood. There is a broad consensus on the relationship between the strength of the variability and such quantities as time-lag, wavelength, luminosity, and redshift. However, evidence on a dependence on the fundamental parameters of the accretion process is still inconclusive. This paper is focused on the correlation between the ultraviolet quasar long-term variability and the accretion rate.2013A&A...560A.104Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/560/A104CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/525/A37 : Variability indexes of QSOs in SDSS Stripe 82 (Meusinger+ 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/560/A104https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/560/A104http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/560/A104https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/560/A104https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/560/A104http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/560/A104GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/560/A104/catalog (Quasar variabilities and accretion rates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/560/A104/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/560/A104/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/560/A104/catalog?GETtext/xml+votable180.050000true0.0511-0.5390.0055555555555555565/4437-4438 4441-4442 4453-4454 4457-4458 4501-4502 4505-4506 4517-4518 4521-4522 4544 4693-4694 4697-4698 4709-4710 4713-4714 4757-4758 4761-4762 4773-4774 4777-4778 5801-5802 7509-7510 6/0-2 12288-12290 17405-17407 17659 17661-17663 17725-17727 17741-17743 17745-17747 17756-17758 17761-17763 17772-17774 17776-17778 17805-17807 17809-17811 17820-17822 17825-17827 17836-17838 17840-17842 17848 17856-17858 17860 17981-17983 17997-17999 18001-18003 18012-18014 18017-18019 18028-18030 18032-18034 18061-18063 18065-18067 18076-18078 18081-18083 18092-18094 18096-18098 18112-18114 18685-18687 18749-18751 18765-18767 18769-18771 18780-18782 18785-18787 18796-18798 18800-18802 18808 18829-18831 18833-18835 18844-18846 18849-18851 18860-18862 18864-18866 18880-18882 19003 19005-19007 19021-19023 19025-19027 19036-19038 19041-19043 19052-19054 19056-19058 19085-19087 19089-19091 19100-19101 19105-19107 19116-19118 19120-19122 19136-19138 19200-19202 19456-19458 19464 23201-23203 23212-23214 23218 30029 30033-30035 30044-30046 36861-36863 49149-49151https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/560/A104?format=asciiOpticaldefaultJ/A+A/560/A104/catalogQuasar variabilities and accretion ratesSeq[1/3916] Sequential numbermeta.recordintprimarySDSSSDSS designation hhmmss.ss+ddmmss.smeta.id;meta.maincharRAJ2000Right Ascension J2000.0 (degree)degpos.eq.ra;meta.mainDEJ2000Declination J2000.0 (degree)degpos.eq.dec;meta.mainzsp[0.7/1.7] Spectroscopic redshift (1)src.redshiftfloatPlateSpectroscopic plate number (1)meta.id;instr.plateintFiberSpectroscopic fiber number (1)meta.number;pos.parallax.spectintMJDMJD of spectroscopic observation (1)time.epochintlogLbolLog Bolometric luminosity (1)log(1e-07W)phys.luminosityfloate_logLbolError in logLbol (1)log(1e-07W)stat.errorfloatlogMbh?
