Best-fit values of the physical luminosity injected in electrons (left) and protons (right), as a function of each source’s disk luminosity. The physical luminosities in the rest frame of the black hole are given by In the upper plots the physical luminosity is given in erg s^-1 and the dotted lines indicate L^phys=L_disk ; in the lower panels it is given in units of the Eddington luminosity L_Edd and the dotted lines indicate L^phys = L_Edd . The best-fit power laws (excluding the upper limits) are shown as solid black lines. For protons, these relations are calculated using only the best-fit results that are incompatible with . These are shown as solid points, while the inverted triangles represent results compatible with within 1 σ. We also cite the result of the Pearson correlation coefficient r, applied to the logarithm of the corresponding variables, and its respective p value. As we can see, all variables present a statistically meaningful moderate power-law correlation with the disk luminosity, except the proton power in the upper right plot.
