Doppler factor for a Fermi blazar sample

We selected 457 blazars (193 flat spectrum radio quasars, 61 low-synchrotron peaked blazars, 69 intermediate-synchrotron peaked blazars and 134 high-synchrotron peaked blazars) from the second Fermi-LAT catalog (2FGL) of {gamma}-ray sources, which have X-ray observations. We calculated the lower limits for their Doppler factors, {delta}{gamma}, and compared the lower limits with the available Doppler factors and the apparent superluminal velocities in the literature.
