Left panels: VI CMD of Be 20, Be 22, Be 29, Be 66, and Be 73. The spectroscopic targets analysed in this study are indicated with filled dots (for cluster members) and empty dots (non-members). Middle panels: effective temperature and surface gravity of the spectroscopic targets (as derived in this study). Right panels: radial velocities and metallicities (both as computed in this study) for the spectroscopic targets. References for photometry: A11: Andreuzzi et al.
