Radial dependence of vertical gravity (upper panel) and effective temperature (lower panel) in our slim disk models for three accretion rates: ṁ  =  0.01, 0.1, and 1, denoted as black, blue, and red respectiverly. Two dashed lines (blue and black) represent models for which we assume that the spin of a black hole equals 0.98. Thin horizontal lines mark the position of horizon and ISCO for rotating (dashed line) and nonrotating black holes (solid line). Points mark annuli for which detailed radiative transfer computations were performed.
