Distribution of the cores’ estimated physical sizes (i.e., diameters). Left panel: overall distribution of core sizes. The vertical dashed black line marks the median value of the distribution (1700 au). For better visualization purposes, the few outliers above 5000 au (∼2%) are not shown. Right panel: same distribution of left panel (black), but overplotted with the core size distributions resulting from better resolved fields (gold, below 1500 au) and less resolved ones (dark green, above 1500 au). The two histograms overlap in the lighter green area.
