Example of application of our full selection function pipeline to map cluster detectability. Top: adopted dust map viewed top-down in galactocentric Cartesian coordinates with the Galactic centre to the right, averaged from z values from –100 to 100 pc. Bottom: as above, but predicting the detection probability of a 2.5 Gyr old, 200 M_⊙ cluster with solar metallicity on a circular orbit. n_∗ and med(σ_ϖ) were predicted with our XGBoost predictor and then fed to our MCMC selection-function model. The white circle in the middle is a masked region, as distances lower than 500 pc were not considered in this study.
