Differential core mass function (ΔN/ΔlogM) for 927 starless cores (purple), 405 candidate prestellar cores and 209 robust prestellar cores. The vertical gray filled area at 0.45 ± 0.15 M_⊙ denotes the estimated 90% completeness level for prestellar cores (see Appendix A). Error bars represent statistical uncertainties ($\sqrt{N}$). A power-law fit to the CMF at the high-mass end (≳1 M_⊙) yields a logarithmic slope of −1.4 ±0.2 (see text).
