Comparison between the clump-averaged estimators for the core separations, specifically the median (top panel) and mode (bottom panel) of the distribution in each clump, and the computed Jeans length. The fragmentation level in the clump is indicated by the symbol sizes, with increasing size going from low (4 ≤ N_cores<8) and intermediate (8 ≤ N_cores<16), up to high (N_cores ≥ 16) core numbers. The dashed lines are drawn as a reference and correspond to the separation equal to ${\lambda }_J^{th}$ (thick line) and 2 × and $0.5\times {\lambda }_J^{th}$ (thin lines), respectively. The gray shaded boxes indicate the amplitude of the distributions of the ratio $l_i^{depr}/{\lambda }_J^{th}$ (see text), and correspond to the interquartile range (dark gray) and the 10th to 90th percentile range (light gray), respectively.
