Cluster Gaia DR3 CMD diagram (IMAGE) The University of Hong Kong Caption Cluster Gaia DR3 CMD (B versus B-R) diagram fitted with a Padova theoretical isochrone (Bressan et al. (2012), Marigo et al. (2013) for adopted cluster parameters (age = 470 +/- 50 Myrs, reddening E(B−V ) = 0.26 +/-0.04, distance = 1.49 +/- 0.13 kpc and metallicity [Fe/H] = 0.03 +/- 0.28). The CSPN is indicated by the red filled symbol. Stars with >80% probability (Cantat-Gaudin et al. 2018) of being a cluster member, where cross-correlated with Gaia DR3 and are plotted as green dots. The CMD includes all stars with pmRA =0 to 4 and pmDec = −8 to −2 mas/yr (most probable cluster members based on mean proper motions) within 15 arcminutes from the cluster’s apparent center.
