Abstract
In the published article, our code to evaluate the γγ opacity due to the BLR radiation field contained a numerical error, due to which all opacities are a factor of 2π too low. The corrected Figures 2-4 are shown below. The conclusions of the paper do not change qualitatively, but the constraints on the location of the γ-ray emission region become tighter. In particular, in the case of 3C279, VHE photons beyond ~300 GeV, must be emitted significantly beyond the BLR, if produced by Compton scattering of BLR photons
