Emergent spectra of the model atmospheres before (dashed lines) and after ray-tracing (solid lines), and emergent spectra of local blackbody emission (dotted line). The models were computed for a fixed effective temperature T_eff = 1, 2, and 2.3 × 10⁷ K (upper, middle, and bottom panel, respectively) for all chemical compositions given by colors, and for a fixed value of surface gravity log(g) = 14.34, which corresponds to an NS mass of 1.9 M_⊙ and a radius of 12.4 km.
