Synthetic emission maps of the reconfinement shock with jet Lorentz factor Γ_j = 10, opening angle Θ_j = 5° and external pressure index η = 0, filled with a toroidal magnetic field and seen from different viewing angles θ_obs. The jet origin is marked with an empty circle, the reconfinement point with a filled circle. The outline of the shock fronts is shown with orange lines. Gray shading indicates the intensity of synchrotron radiation, while the blue bars mark the electric polarization vector of length proportional to the polarization degree.
