Principle demonstration of the effect of a variable partial covering absorption on an absorbed powerlaw with photon index Γ = 1.7 and ISM absorption . We assume a covering fraction of 0.9 and a varying equivalent hydrogen column density, N_H, of the partialcoverer, ranging from , implying only ISM absorption, to . The uncovered fraction (here, 1 − f_c = 0.1), is shown as a black dash-dotted line. The covered, absorbed component is shown in dashed lines, with colors corresponding to different N_H. The sum of the covered and uncovered fractions is shown in the solid colored lines. With increasing N_H of the partial coverer, we first see a diminution primarily of Band 1. The partial covering fraction leads to a “floor” for the flux value in band 1, while band 2 and band 3 continue to decrease with an increasing column. This illustration follows a similar illustration in Hirsch et al. (2019).
