Notes: (1) median FUV fluxes in the cluster with uncertainties (16^th and 84^th percentiles of the distribution), (2) ages compiled from various references with uncertainties reflecting the age spread in the cluster, (3) disc fractions with standard errors compiled from various sources.

†No information on the age spread is provided and a spread of 2 Myr is assumed.
