cds-question@unistra.fractive-galactic-nucleigamma-ray-astronomyquasarsbl-lacertae-objectsThis paper presents light curves as well as the first systematic characterization of variability of the 106 objects in the high-confidence Fermi Large Area Telescope Bright AGN Sample (LBAS). Weekly light curves of this sample, obtained during the first 11 months of the Fermi survey (2008 August 4-2009 July 4), are tested for variability and their properties are quantified through autocorrelation function and structure function analysis. For the brightest sources, 3 or 4 day binned light curves are extracted in order to determine power density spectra (PDSs) and to fit the temporal structure of major flares. More than 50% of the sources are found to be variable with high significance, where high states do not exceed 1/4 of the total observation range. Variation amplitudes are larger for flat spectrum radio quasars and low/intermediate synchrotron frequency peaked BL Lac objects. Autocorrelation timescales derived from weekly light curves vary from four to a dozen of weeks.2010ApJ...722..520Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/722/520CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/538/A26 : BL Lac objects beyond z=1.3 (Rau+, 2012)J/ApJS/194/29 : Observations of blazars at 15GHz (Richards+, 2011)J/ApJ/716/30 : SED of Fermi bright blazars (Abdo+, 2010)J/ApJ/709/1407 : SED of the Fermi blazars (Li+, 2010)J/ApJ/700/597 : FERMI LAT detected blazars (Abdo+, 2009)J/ApJS/183/46 : Fermi/LAT bright gamma-ray source list (0FGL) (Abdo+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/722/520https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/722/520http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/722/520https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/722/520https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/722/520http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/722/520GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/722/520/table1 (Variability indices and amplitudes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/722/520/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/722/520/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/722/520/table1?GETtext/xml+votable180.050000true4.3992383-5.21160190.0055555555555555566/579 1701 2122 2295 2331 2414 2836 3431 4695 4770 5162 5423 5817 5918 6018 6088 6368 6507 6777 6963 7045 7346 7426 7446 7896 8299 8466 8915 9075 9460 9612 10422 11081 11153 11649 12604 12619 13485 13664 13927 14854 15969 16027 16298 16720 16796 17186 17364 17579 17857 17927 18624 19370 19398 19622 19831 20099 21121 23897 24084 24608 24845 25302 25677 25818 26131 26292 27060 27243 27433 28342 28479 28492 28517 29016 31663 31894 32311 33774 33825 34123 34209 34461 34572 35079 35281 35706 35786 36058 36151 36554 36941 37529 42980 43262 44069 44247 44908 45011 46055 46251 46740 47014 47375 48123 49071https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/722/520?format=asciiGamma-raydefaultJ/ApJ/722/520/table3Tabulated data of the weekly flux light curves reported in figures 1 and 2recnoRecord number assigned by the VizieR team.
