Jet‐to‐counterjet flux density ratio, ﹩S^{*}( \theta ^{*}) / S^{*}( \pi -\theta ^{*}) ﹩, at radio frequencies, as a function of the viewing angle ﹩\theta ^{*}﹩. Black and gray lines correspond to values ﹩\Gamma _{c}=10﹩ and 3, respectively—the values of ﹩\Gamma _{c}﹩ are provided near the respective curves. The black (gray) solid line corresponds to the radiation from an anomalous boundary shear layer with the radial profile of eq. (14) and ﹩\Gamma _{j,1}=15﹩ (﹩\Gamma _{j,1}=4.5﹩). The dash‐dotted line corresponds to the radiation from a monotonic boundary layer with the radial profile of eq. (14) and ﹩\Gamma _{j,2}=1﹩. The dashed line corresponds to the model with a uniform boundary layer with a Lorentz factor ﹩\Gamma _{j,3}=10﹩.
