Normalised accretion rates, , for different particle sizes with friction time τ_f = 1 and τ_f = 0.01, as indicated by respectively asterisks and diamonds. The grey curves correspond to those shown in Fig. 6 and similarly the transition mass is indicated by a full grey circle. In the Hill branch, larger particles, τ_f = 1, get accreted as efficiently as particles with friction time τ_f = 0.1 (see Fig. 6), but in the drift branch they never get accreted at the full drift rate. On the other hand, small particles, τ_f = 0.01, get efficiently accreted in the drift branch, but less so in the Hill regime.
