Bolometric (top) and 3–9 keV (bottom) luminosities in function of the mass accretion rate ṁ_in onto the black hole. This plot is extracted from Fig. 5, done with a 10% hard tail (right). The colors are for different values of the transition radius r_J. Four different regimes are shown. Also, the r_J = r_in has been drawn in dashed black to be visible at low accretion rate in the bottom panel.
