Comparison of single scattered (dashed lines) and multiple scattered (solid lines) solutions computed with approximation-II of Bommier (1997b). The model parameters are (T,   a,   ϵ,   r) = (10⁴,   10^-3,   10^-3,   0) and the magnetic field parameters are (Γ,   θ_B,   χ_B) = (1,   30°,   0°). Panel a) corresponds to collisionless case (Γ_E/Γ_R = 0) and panel b) to an equal mix of type-II and III scattering (Γ_E/Γ_R = 1).
