The top panel shows the mass functions from those Pop. III.1 simulations in which fragmentation occurs. In all cases the mass function is plotted at the point at which the total mass of gas converted to sink particles is 100. Note that as accretion is ongoing, and the system is still young ($t \sim 1000$ yr), these will often not be the final masses of the sinks. The mass functions in the individual simulations differ substantially, although the combined mass function, shown in the bottom panel, exhibits a broad and flat distribution between masses of 0.4 and 20 .](fig02a){height="2.5in"}
