cds-question@unistra.frbl-lacertae-objectsquasarsspectral-energy-distributiongamma-ray-astronomyx-ray-sourcesactive-galactic-nucleiWe complied the optical, X-ray, and {gamma}-ray data for 54 Fermi blazars and studied the relationship between the broadband spectral index {alpha}_ox_ and {alpha}_x{gamma}_, as well as the relationship between the intrinsic composite spectral indices {alpha}_xox_ and {alpha}_{gamma}x{gamma}_ for this sample. The relationship between {alpha}_xox_ and {alpha}_{gamma}x{gamma}_ reveals that flat spectrum radio quasars and low-energy peaked BL Lacertae follow a continuous trend, which is consistent with previous results, whereas high-energy peaked BL Lacertae follow a separate distinct trend. Even so, a unified scheme is also revealed from {alpha}_xox_-{alpha}_{gamma}x{gamma}_ diagram when all three subclasses of blazars are considered.2010ApJ...709.1407Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/709/1407CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/194/29 : Observations of blazars at 15GHz (Richards+, 2011)J/ApJ/700/597 : FERMI LAT detected blazars (Abdo+, 2009)J/ApJS/183/46 : Fermi/LAT bright gamma-ray source list (0FGL) (Abdo+, 2009)J/ApJ/657/706 : EGRET blazar gamma-ray spectrum (Nandikotkur+, 2007)J/A+A/375/739 : Hard X-ray properties of blazars (Donato+, 2001)J/ApJ/525/127 : RGB sample of BL Lacertae objects (Laurent-Muehleisen+, 1999)J/A+A/311/384 : ROSAT observations of BL Lacertae objects (Lamer+ 1996)J/A+A/281/355 : X-ray AGN content of Molonglo 408MHz survey (Brinkmann+ 1994)J/other/PASAu/10.310 : Parkes-Tidbinbilla radio sources (Duncan+ 1993)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/709/1407https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/709/1407http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/709/1407https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/709/1407https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/709/1407http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/709/1407GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/709/1407/table1 (The sample of Fermi blazars with both {alpha}_x_ and {alpha}_{gamma}_)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/709/1407/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/709/1407/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/709/1407/table1?GETtext/xml+votable180.050000true12.6721558-9.48478060.0055555555555555566/579 2295 2414 2836 3431 4695 4770 5423 5817 5918 6018 6507 7426 7896 8915 9460 9612 10422 11212 12619 13927 15969 16298 17579 19398 19831 20099 23121 24084 24608 24845 25302 25677 26131 26292 27060 28479 28492 28517 31663 31894 32311 34123 34461 34572 35079 35786 36058 36554 44247 44908 46740 47014 47375https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/709/1407?format=asciiGamma-rayX-raydefaultJ/ApJ/709/1407/table1The sample of Fermi blazars with both {alpha}_x_ and {alpha}_{gamma}_ONameOther namemeta.idcharaxoxComposite spectral index {alpha}_xox_spect.indexfloatrecnoRecord number assigned by the VizieR team.
