Spectra (top row) and PD profiles (bottom row) of the disk direct radiation observed at infinity for two BH spins, a = 0 (left) and 0.998 (right), and three values of the observer’s inclination, θ = 13° (cyan), 51° (orange), and 74° (green), with the disk atmosphere assumed to be in CIE. The solid lines show the results obtained for N_H = 10²⁴ cm⁻² and Ṁ = 0.1 Ṁ_Edd, the dashed lines those obtained for N_H = 10²⁴ cm⁻² and Ṁ = 0.3 Ṁ_Edd, and the dash-dotted lines for N_H = 5 × 10²⁴ cm⁻² and Ṁ = 0.1 Ṁ_Edd. All other parameters are the same as in Fig. 5.
