Time-distance histograms of encounter candidates between HMXBs and open clusters in the past 100 Myr. Dotted white lines represent the median distance, and the 1 to 3σ intervals are represented from dark red, to red, to orange. In green is indicated the physical radius of the clusters computed from their extension in the plane of the sky and their parallax. Their age range obtained through isochrone fitting is indicated in grey. The black vertical plain and dotted lines provide our estimation of the age since supernova in each binary-cluster encounter candidate.
