Fraction of simulated clusters recovered as a function of R_GC and Z divided into multiple different mass and ages ranges, and compared against the distribution of OCs in HR24 within those ranges. Each row shows clusters in a different mass range, indicated by the label on each subplot. The subplots in the left column show young clusters with log t < 8.5, while subplots in the right column show old clusters with log t > 8.5. Although proper motions only have a small impact on cluster detectability, we nevertheless only show the detection results of simulated clusters with proper motions |μ_α*| < 2.5 and |μ_δ| < 2.5, providing a slightly more conservative estimate on cluster detectability at these locations.
