Excess fraction as a function of central object mass for assumed ages of 5 (Top) and 10 Myr (Bottom), over a violin graph of the ${\langle 1-q_i^{\left(k\right)}\rangle }_i$ distributions and mass density. Same features as Fig. 6 are shown. Linear regression was performed for the entire sample keeping flagged sources in unWISE images (see Sect. 3.1). The original fractions for the cleaned sample are shown in the background with transparency for comparison.
