Mass vs size distribution of the recovered cores from the simulation with a mean density of 10³ H/cm³ (left) and ⟨ρ⟩ = 10⁴ H/cm³ (right) are shown in comparison with the core samples of Könyves et al. (2015) (solid grey shaded region) and Sanhueza et al. (2019) (grey hatched region). The contours cover 90% of the recovered cores from the simulations. The dashed line represents the mass–size relation from Elmegreen & Falgarone (1996), and the solid line illustrates the power-law behaviour observed in simulations across different scales by Colman et al. (2024).
