As in Fig. 4, but assuming different values for BH spin. In both panels, the coronal temperature is set to kT_e = 60 keV and the inner radius of the corona is set to the ISCO value of the corresponding spin configuration. The left panel compares BH spins with R_disk = 25R_G for different wedge opening angles (α). The right panel compares BH spins for different values of the inner radius of the AD (R_disk). The Π increases with increasing spin.
