Spectra of the component reflected by the toroidal material obscuring the central source. Panel (a): Case of cold, non-ionized plasma. Panel (b): Fully ionized case (but note that Compton up-scattering is not taken into account). The thin black line is the primary emission (we assumed a thermal Comptonization of kT_e = 100 keV), the thick black line shows the angle-averaged reflected component, and the colored lines show the dependence of the reflected spectra on the viewing angle, i, for i < 50°.
