Self-consistent spectra from a homogeneous slab corona of τ_T = 0.4 above a disc as observed at inclination i = 60°. The red and blue curves correspond to log ξ = 1 and 3, respectively. The dotted lines show the Comptonization continuum, the dashed lines show the reflection xillverCp spectrum together with reprocessed blackbody emission, and the solid lines give the total spectrum. The reflection spectra have been re-binned at a resolution Δ log E = 0.025. The bolometric luminosity of the reflection spectrum here is smaller than that of the Comptonization continuum because part of the reflected/reprocessed emission is Compton scattered in the corona.
