Spectra observed at i = 30° from a disk-corona system for the accretion-disk parameters corresponding to those in our model 3 and a slab corona, with (a) τ = 0.007 and kTe = 250 keV and (b) τ = 0.75 and kTe = 25 keV, computed using the Monte Carlo code of Niedźwiecki (2005). The solid curves show the total spectra, including the thermal disk emission. The dotted magenta curves represent the reflected component, and the dot-dashed green curves show the direct coronal emission. The reflection is calculated assuming a perfectly reflecting disk. For the nonrotating black hole adopted here, light-bending effects are negligible, and the difference between the reflected and direct components arises from the local anisotropies of radiative processes.
