Relative mass loss induced by stellar encounters a) as a function of time for model CK1 for the case of ϵ_SFE = 1.0; b) as function of the SFE for model CK1; and c) as a function of the initial cluster density. In b), no data points for SFEs of 10% and 20% are plotted, as the bound masses here are so low and the errors are large, such that no meaningful values for the differences can be obtained. In c) the different symbols give the values obtained from the simulation results for ϵ_SFE = 0.3 (circle), ϵ_SFE = 0.7 (square), and ϵ_SFE = 1.0 (triangle). The curve shows the approximation of (log   (ρ))^3/2.
