Fig. 3


X-ray extinction (solid black line), absorption (solid red line), and scattering (dashed blue line) cross sections per H nucleon for the Mathis et al. (1977) dust model (0.005 ≤ a ≤ 0.25 μm). The scattering cross section contributes significantly to the extinction, but it does not significantly modify the absorption features in the post-edge. This plot is characteristic of olivine.
