Cumulative distribution functions (CDFs) of the peak density of gas clumps at the time of sink formation (ρ_peak), normalized to the threshold density for sink creation (ρ_th). The CDFs are computed by counting all sink particles from strongly turbulent GMCs (S1–S3), where the convergence in the SFEs is worse than in the weakly turbulent GMCs. Different colors and line styles correspond to CDFs from runs with different spatial resolutions, as indicated in the legend. Note that most of the sinks are created near ρ_th when the AMR resolution is high.
