Two Years of Monitoring of Blazars with the OVRO 40 m Telescope at 15 GHz in Support of Fermi-GST


We have continued our monitoring program of ~1200 sources with the Owens Valley Radio Observatory 40 m Telescope. Most of the sources are part of the Candidate Gamma-Ray Blazar Survey (CGRaBS). We have also been observing Targets Of Opportunity triggered by gamma-ray detections and participating in multiwalength campaigns lead by Fermi-GST. Regular program sources are observed twice a week and have been observed for ~24 months at 15 GHz. We use these light curves to study the radio variability and its relation with optical properties. A significant fraction of the bright AGNs detected by Fermi-GST are in our program, which will allow for correlations between the radio and gamma-ray behavior for a number of sources. Here we present some example light curves, describe the tools used to study the variability and present some preliminary variability statistics for the sample.
