Notes. Here kTbb,e,0 are the blackbody, electron or seed temperatures for the blackbody and Comptonization models, Γ is the power-law photon index, Ecut,fold are the cutoff and fold energies for the cutoff power-law component. The “low” and “high” indices refer to the two spectral components. [keV].
