Spectral energy distribution curves with different eDFs and different spins in turbulent heating (left) and reconnection heating (right) models. From top to bottom: black hole spins are −0.9375, 0, and 0.9375, respectively. The black curves adopt the thermal eDF, while the red curves employ variable κ eDF. For the comparison, variable κ eDF using the R − β model with R_h = 1 and 160 are presented as blue and green curves, respectively. The solid curves represent average values and the shaded regions denote the standard deviation relative to the average values. The dash-dotted vertical lines correspond to 43 GHz, 86 GHz, 230 GHz, and 136 THz.
