Panel a: red line shows the twice-broken power-law, radial emissivity profile fitted to 1H0707–495 by Wilkins & Fabian (2011), see text. The blue line shows the emissivity profile produced by the X-ray source with h_min = 2, h_max = 10, r_c = 30, and Γ = 3.1. Panel b: reflection spectra for the emissivity profiles shown in panel a, and for Γ = 3.1, ξ = 53, A_Fe = 9, i = 54° and r_in = r_ISCO; the difference of spectral shapes is only due to different amounts of relativistic distortion corresponding to the difference of the radial profiles.
