Cumulative mass histograms and models for the control (left) and moderate turbulence (right) simulations and for seven different models: SPL, STPL, TPL, BCPL, BPL, VTPL, and TSPL. Fit parameters to the best models can be found in Table 2. The bottom histogram shows the true values, with each plot above offset by a factor of 10^1.5 for convenient visualization. The shape of the planetesimal mass function is generally the same in the control (pure SI) simulation as in the moderate turbulence simulation. The broken power-law model for the mass function, shown in dark blue, is statistically favored according to the Bayesian and Akaike information criteria for all of our simulations.
