We generalize previous calculations of the beaming pattern of photons produced by inverse Compton scattering. For an isotropic distribution of soft photons upscattered by nonthermal electrons with a power-law density distribution n(γ) ∝ γ-p , embedded in a plasma moving with relativistic bulk speed, we show that the observed radiation intensity is proportional to δ3+p , where δ is the Doppler boosting factor. This general result agrees with previous computations performed in the Thomson limit. Assuming that the soft photons originate in the broad line region, we demonstrate that the Thomson approximation describes adequately the MeV peak emission of the strong line emitting EGRET-detected blazars, while the GeV spectrum is significantly affected by Klein-Nishina effects, being softer than that calculated in the Thomson limit. We further show that the change in spectral index of the inverse Compton emission between the MeV to GeV ranges can exceed the value of 0.5 predicted by computations performed in the Thomson limit.
