Histogram of Eddington ratios of X-ray detected sources, colour-coded based on our classification scheme in FRII (red), FRI (blue), FRI/FRII (green) and COM AGN (black). Top panels: radiative Eddington ratio (left) and the redshift-dependence corrected Eddington ratio (right). Bottom panels: radiative and kinetic Eddington ratio (left) and the redshift-dependence corrected Eddington ratio (right). The median values of the Eddington ratio for each population are shown as lines: dotted red lines show FRIIs, dashed blue show FRIs, dashed-dotted green show FRI/FRIIs, and solid black lines show COM AGN.
