Top left: Temperature profile normalized by the black hole temperature T_* as function of the radius of the accretion disk (normalized by the Schwarzschild radius of the black hole). Bottom left: Critical accretion rate of the accretion disk as a function of the radius of the disk (normalized by the Schwarzschild radius of the black hole). Top right: Emitted intensity as a function of the wavelength for each of the 100 disk radius (in gray) and summed up (in red). Bottom right: Theoretical flux as a function of the wavelength for a SMBH with M_*, p = 1.5 × 10⁸ M_⊙ and an accretion disk with inner radius of r_int, p = 3.38 × 10⁻³ pc and an outer radius of r_out, p = 6.80 × 10⁻³ pc (all 100 radii are shown in gray and summed up in red).
