Peak mass of the sink mass spectrum plotted against the mass of the first Larson core calculated with the eos we used in the simulations. The peak mass is read from the stellar distribution, with the bin size as error. The error bars from literature results are larger as they have lower statistics and higher fluctuations in the spectrum. The mass of the first Larson core is read from Fig. 7, with error bars indicating the mass range with the probable n₀ range. Whenwe examine this by eye, there is a correlation M_peak ~ 5M_Larson. We also performed a simple linear regression, without considering the errors, to determine the scaling factor, and this led to .
