Cumulative mass distributions of the sink particles at the end of a simulation of our fiducial model (blue line), one with the improved sink particle creation criteria (orange line), one in which mutual sink particle accretion is permitted (red line), and one where the dust density threshold for sink particle creation is five times smaller than the fiducial value (purple line). In addition, the mass distribution of gravitationally unstable clumps identified by a clump finding algorithm is shown (green line). The distribution of sink particle masses is largely independent of whether the fiducial or the improved sink particle creation criteria are employed. However, the clump finding algorithm discovers more high- mass and fewer medium-mass clumps, while even more high-mass and fewer low-mass sink particles emerge in the simulations including sink particles mergers and a reduced dust density threshold, respectively.
