Predicted spectral energy distributions of the radiation generated by an AR boundary layer (﹩\Gamma _{c}=10﹩, ﹩\Gamma _{j,2}=20﹩) of a kiloparsec‐scale jet assuming ﹩\gamma _{\mathrm{eq}\,}=10^{8}﹩, for observing angles ﹩\theta ^{*}=5^{\circ }﹩, 30°, 60°, and 90°. Indices 1 and 2 denote the spectral components associated to the power‐law isotropic energy distribution and to the monoenergetic part, respectively. Absorption of VHE gamma‐rays during the propagation to the observer is neglected.
