Radial profiles of the disk surface temperature (left) and density (right) used in CLOUDY computations (see equation 1 and equations (A1)-(A3) in Taverna et al. (2021)) for a nonrotating BH (cyan) and a maximally rotating BH (orange), and for two values of the mass accretion rate, Ṁ = 0.1 (solid) and 0.3 Ṁ_Edd (dashed). In both cases, a BH mass of 10 M_⊙ and a hardening factor of f_col = 1.8 are considered. The vertical dotted lines indicate the location of the ISCO for the two spin values.
