Similar to Figure 9, but for the Eddington ratio distribution instead of the luminosity function. The Eddington ratio is calculated using the calibration of H. Netzer (2019) for the bolometric luminosity and the M_BH–σ relationship of J. Kormendy & L. C. Ho (2013). The vertical dotted line shows λ = 10⁻³, the Eddington ratio we use for defining occurrence rates of AGN in Figure 13.
