Line profile for the damped sine-wave velocity case with higher spatial resolution, but lower angular resolution than in Fig. 5. The spatial resolution is n_r = 129, n_θ = 65, and n_φ = 65, and the angular resolution is reduced to n_Ω = 32 × 24. The comoving mean intensity J_λ for each voxel on the surface (there are 65 × 17 = 1105 of them) is plotted as a function of λ (red lines). The green curve is the 1D result using the methods of Baron & Hauschildt (2004) and Knop et al. (2009b,a). Here the scattering fraction is ϵ = 1 for computational expediency, and the line strength is Γ = 100.
