Top panels: synchrotron emission maps obtained using the evolving particle spectra with an initial power-law index p = 6 for the UNI-B case at t/t_a = 3.75 projected on the sky plane X′–Y′. These maps are produced for a direction along a line of sight inclined at 20° with the jet axis at observing frequencies of ν/ν_sc≈ 8.2 × 10⁴, 8.2 × 10⁶, and 8.2 × 10⁸, where ν_sc = 122 Hz is the frequency scale. Middle panels: corresponding inverse-Compton emission maps at observing energies of E/hν_sc≈ 7.9 × 10¹⁶, 7.9 × 10¹⁸, and 7.9 × 10¹⁸, where h is the Planck constant and the other model parameters are the same. The specific intensity is normalized to I_νsc = 7.46 × 10⁻¹⁵ ergs s⁻¹ cm⁻² Hz⁻¹ str⁻¹, corresponding to γ_max = 10⁸. Bottom panels: density ρ/ρ₀ (left panel) and pressure P/P₀ (right panel) maps integrated along the same line of sight.
