cds-question@unistra.frquasarsbl-lacertae-objectsspectral-energy-distributionSimultaneous broadband spectral and temporal studies of blazars are an important tool for investigating active galactic nuclei (AGN) jet physics. We study the spectral evolution between quiescent and flaring periods of 22 radio-loud AGN through multiepoch, quasi-simultaneous broadband spectra. For many of these sources these are the first broadband studies. We use a Bayesian block analysis of Fermi/LAT light curves to determine time ranges of constant flux for constructing quasi-simultaneous spectral energy distributions (SEDs). The shapes of the resulting 81 SEDs are described by two logarithmic parabolas and a blackbody spectrum where needed.2016A&A...591A.130Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/591/A130CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/591/A130https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/591/A130http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/591/A130https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/591/A130https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/591/A130http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/591/A130GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/591/A130/table1 (Sources used in the SED catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/591/A130/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/591/A130/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/591/A130/table1?GETtext/xml+votable180.050000true32.6925-51.01720.0055555555555555566/33774 33827 34123 34209 34264 34461 34517 34528 34572 35079 36941 37385 41072 43366 43380 44069 45178 46055 47014 47016 47375 47540https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/591/A130?format=asciidefaultJ/A+A/591/A130/table1Sources used in the SED catalogrecnoRecord number assigned by the VizieR team.
