The fraction f_ej(M) of runaway stars for M > 10   M_⊙ at t ≈ 3 Myr cluster age as obtained from the four computations of Paper I (cf. Fig. 4 of Paper I). We use the same symbols as in Fig. 4 of Paper I to indicate that they are obtained from direct N-body computations starting with different initial realizations of the R136 model employed in Paper I. The central solid line represents the best-fit line to the data that asymptotes to unity (see Sect. 4). The upper and the lower dashed lines limit the error in the fitting. The dotted line is the best-fit single power-law to the entire data which is truncated at f_ej(M) = 1 (see Sect. 4).
