Surface brightness profile across the western half of RN. We applied the model to different frequencies at different resolutions: 3 GHz at 3.5″ (orange), 1.5 GHz at 8″ (blue), 150 MHz at 8″ (red), and 45 MHz at 15″. Left: log-normal magnetic field distribution (B₀ = 0.3 μG, log(σ) = 1.65) and Ψ = 12° projection. Right: log-normal magnetic field distribution (B₀ = 0.3 μG, log(σ) = 1.65), Ψ = 12° projection and additional wiggle-effect with σ = 15 kpc.
