Proper motions and colour-magnitude diagram of the members of the open cluster IC 2602. Top panel shows the proper motions of the cluster members (in black) after a selection based on the parallax and the proper motions themselves. Bottom panel shows the Gaia G-mag versus BP-RP colour–magnitude diagram of the same stars with a BASTI-IAC isochrone of 35 Myr superimposed. In both panels, green symbols represent the target of this study.
