Cumulative mass distributions at the end of simulations with the fiducial (left panel) and the improved sink particle creation criteria (right panel) but excluding mutual sink particle accretion. The mass distributions are fitted with an exponentially tapered power law (see Eq. (8)). The uncertainty of the cumulative numbers N_>(M) is assumed to be proportional to N_>(M)M^γ, with fits for different choices of γ being shown. While for the fiducial creation criteria γ = 0 yields the fit with the largest exponents of power-law part α and exponential tapering β, the two exponents are highest if γ = −0.5 for the improved creation criteria. In both cases, this comparatively steep power law appears to fit the numbers at intermediate masses best.
