Ṁ_input versus Ṁ_R calculated from the grid also used to construct Fig. 6 and Eq. (6). The dotted line indicates where the quantities are equal, the dashed lines show a factor three difference w.r.t. this relation. The listed δ,μ, and σ are, respectively, the mean values, the standard deviations, and the maximum absolute values of log (Ṁ_R/Ṁ_input). We specify these quantities for the full grid (plotted in grey), and for the grid points inside the interval  [10^-7;10^-5]  M_⊙  yr^-1 (plotted in black). The histogram in each panel shows the peak-normalised distribution of log (Ṁ_R/Ṁ_input).
