Fraction of simulated clusters recovered compared to the input dust distribution in this study. Top: fraction of all simulated clusters recovered in this work as a function of l and b. Clusters were binned in bins of size 1° × 1°. Grey circles show the distribution of high-quality OCs in HR24 with CST > 5, d > 3 kpc, and a CMD class of better than 0.5. Bottom: as above, but instead showing the total Green et al. (2019) extinction in the V band at a distance of 10 kpc overlaid with real OCs.
