Reflection spectra in the non-relativistic case and a neutral accretion disk for three models; the inclination angle increases from left to right. The incident power-law spectrum is the black curve; the xillver, pexrav, and a Monte Carlo simulation are shown as red, blue, and yellow curves, respectively. We use wilm abundances (Wilms et al. 2000), except for xillver for which we use grsa abundances (Grevesse & Sauval 1998). The highlighted area shows the energy band of the Compton hump, which is used to calculate the reflection strength.
