SAD configurations, settled from r_in = 1 with α_v= 0.1, fed with an increasing ṁ_infrom left to right: 0.01, 1, 100. Top panels: disk effective temperature T_eff (solid lines) and ratio q_adv∕q_turb (dashed lines). Bottom panels: associated disk spectra. The dashed lines are the spectra emitted from each disk annulus whereas the solid black lines are the total integrated spectrum. A red color (in dots and spectra) describes annuli dominated by advection, whereas a green color (triangles and spectra) describes a negative advection term (see text).
