Complementary cumulative distribution function of cores. Shown are the total population of cores (left) and those cores meeting the virial condition E_th < 0.5E_kin (right), for a mean density of ⟨ρ⟩ = 10³ H/cm³. The data for the core populations are depicted as solid lines, whereas the estimated slopes for the MLE method are illustrated as dashed lines. The black curves represent observations from ALMA.
