Left: Accretion rate (log ṁ/ṁ_Edd) as a function of the Eddington ratio (log λ_Edd). The solid line show the identity line. The bottom panel shows the difference between log ṁ/ṁ_Edd and the identity line. Middle: Same but replacing the x-axis with the sum of log λ_Edd and a polynomial function of the inclination angle to account for the anisotropy in the emission (see text for more details). The colour maps corresponds to μ = cos i. Bottom right: Distribution of the differences between the y-axis and the x-axis in the left and middle panels (blue and red histograms, respectively)
