Data from both the first 11 months (1FGL) and the first 2 years (2FGL) of the Fermi mission were used to investigate these sources' {gamma}-ray properties. We use the ratio of the {gamma}-ray-to-radio luminosity as a measure of {gamma}-ray loudness. We investigate the relationship of several radio properties to {gamma}-ray loudness and to the synchrotron peak frequency. There is a tentative correlation between {gamma}-ray loudness and synchrotron peak frequency for BL Lac objects in both 1FGL and 2FGL, and for flat-spectrum radio quasars (FSRQs) in 2FGL. We find that the apparent opening angle tentatively correlates with {gamma}-ray loudness for FSRQs, but only when we use the 2FGL data. We also find that the total VLBA flux density correlates with the synchrotron peak frequency for BL Lac objects and FSRQs. The core brightness temperature also correlates with synchrotron peak frequency, but only for the BL Lac objects. The low-synchrotron-peaked (LSP) BL Lac object sample shows indications of contamination by FSRQs which happen to have undetectable emission lines. There is evidence that the LSP BL Lac objects are more strongly beamed than the rest of the BL Lac object population.2012ApJ...757...25Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/757/25CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/562/A64 : Fermi detection of BL Lac objects (Wu+, 2014)J/ApJS/208/17 : 2nd Fermi LAT cat. of gamma-ray pulsars (2PC) (Abdo+, 2013)J/A+A/541/A160 : Planck + X/{gamma} observations of blazars (Giommi+, 2012)J/ApJS/199/31 : Fermi LAT second source catalog (2FGL) (Nolan+, 2012)J/MNRAS/424/2832 : Pulsars in {gamma}-ray sources (Lee+, 2012)J/MNRAS/424/L64 : AGN/pulsar distinction for 2FGL sources (Mirabal+, 2012)J/ApJ/753/83 : Associations to 1FGL sources (Ackermann+, 2012)J/ApJ/744/177 : VLBA 5GHz observations of Fermi/LAT AGNs (Linford+, 2012)J/ApJ/743/171 : The 2LAC catalog (Ackermann+, 2011)J/ApJ/742/66 : New Fermi/LAT extragalactic sources (Teng+, 2011)J/ApJ/742/27 : 15GHz and jet properties of MOJAVE blazars (Lister+, 2011)J/ApJ/741/30 : Radio/{gamma}-ray correlation in AGN (Ackermann+, 2011)J/ApJ/740/98 : Synchroton peak for blazars and radio galaxies (Meyer+, 2011)J/A+A/535/A69 : AGN Fermi/LAT {gamma}-ray and 37GHz fluxes (Nieppola+, 2011)J/ApJS/194/29 : Observations of blazars at 15GHz (Richards+, 2011)J/ApJ/722/520 : Gamma-ray light curves of Fermi blazars (Abdo+, 2010)J/ApJ/722/L7 : Fermi/LAT detected MOJAVE AGNs (Pushkarev+, 2010)J/ApJ/718/587 : The Fermi-AT20G catalog (Mahony+, 2010)J/ApJ/716/30 : SED of Fermi bright blazars (Abdo+, 2010)J/ApJ/715/429 : First Fermi-LAT AGN catalog (1LAC) (Abdo+, 2010)J/ApJ/709/1407 : SED of the Fermi blazars (Li+, 2010)J/ApJS/188/405 : Fermi-LAT first source catalog (1FGL) (Abdo+, 2010)J/AJ/138/1874 : MOJAVE.
