Upper panel: window RA vs. Dec centered on the position of M 67 by Donor et al. (2020), Cantat-Gaudin & Anders (2020) and Hunt & Reffert (2023). The gray circles are the stars used in HDB-SCAN to search for members of M 67. The blue circles are the members obtained with the HDBSCAN code. The caption indicates the probability of each star belonging to the OC according to the size of the blue circle. Lower-left panel: stars with a probability of belonging to the OC greater than 80% according to our results (blue circles) and the results of Hunt & Reffert (2023, red triangles). Lower-right panel: stars with a probability of belonging to the OC greater than 80% according to our results (blue circles) and the results of Cantat-Gaudin & Anders (2020, red triangles).
