Gaia DR2 CMD for high-probability members of a “typical” UBC cluster, UBC 94. For reference, catalogued stars are named in the diagram. The green solid line represents the preferred isochrone fit according to Cantat-Gaudin et al. (2020, 280 Ma, AV = 1.32). The purple dotted line is an alternative fit with a 150 Ma, AV = 1.7 isochrone. The lack of evolved stars allows for very different solutions.
