Our samples include 714 sources with PTF data and 1244 sources with CRTS data. We calculate the intrinsic modulation index to quantify the optical variability amplitude in these samples. 2014MNRAS.439..690H https://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/439/690 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to J/ApJS/175/97 : CGRaBS: survey of gamma-ray blazar candidates (Healey+ 2008) J/ApJ/715/429 : First Fermi-LAT AGN catalog (1LAC) (Abdo+, 2010) J/ApJ/743/171 : The 2LAC catalog (Ackermann+, 2011) J/ApJS/194/29 : Observations of blazars at 15GHz (Richards+, 2011) J/MNRAS/438/3058 : 15GHz variability of gamma-ray blazars (Richards+, 2014) https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/439/690 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/439/690 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/439/690 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/439/690 https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/439/690 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/439/690 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/MNRAS/439/690/blazars (The blazar samples) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/439/690/blazars? https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/439/690/blazars? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/439/690/blazars?
