Cascade contributions for the source at the redshift z = 0.14 and for a turbulent IGMF with Kolmogorov spectrum with a strength of B = 10⁻¹⁵ G and maximum scale of L_B = 10 Mpc (corresponding correlation length λ_B ≈ 2 Mpc). The jet opening angle was assumed to be θ_jet = 5°, and the observer was at an angle θ_obs = 3° with respect to the jet axis. Red solid lines is for CRbeam code, blue dashed lines is for CRPropa code and green dash-dotted lines: the ELMAG code. Line labels indicate the constraints on the source activity time dt and angular distance from the source Ѳ that were used when constructing the cascade signal. The label “jet” denotes the cascade signal without constraints on dt (dt = ∞) and θ (θ = 2π). For comparison, we also added a cascade spectrum in the absence of a magnetic field (label “full”).
