Excess fraction as a function of central object mass for ages 5 (Left) and 10 Myr (Right), over a violin graph of ${\langle 1-q_i^{\left(k\right)}\rangle }_i$ distributions and mass density. Error bars were obtained from 95% and 68% (or 2 and 3σ respectively) confidence intervals, calculated using the quantiles of the ${\langle 1-q_i^{\left(k\right)}\rangle }_i$ distributions (see Sect. 3.2). Red dots indicate the median of the distribution, adopted as the disk fraction. The numbers of objects included in each mass bin are indicated. Background shading is used to delineate mass bins. These distributions were obtained by removing the sources flagged in the unWISE images (see Sect. 3.1).
