As in Fig. 4, but assuming different values for the AD internal radius (R_disk) in the baseline configuration. In both panels, the coronal temperature is set to kT_e = 60 keV and the wedge opening angle to α = 30°. The left panel shows the a = 0 and R_corona = 6R_G scenario. The difference between R_disk = 12R_G and R_disk = 6R_G is small. The right panel shows the a = 0.998 and R_corona = 1.24R_G scenario. Here, the difference between R_disk = 12R_G and R_disk = 1.24R_G is much higher.
