Notes. The first column gives the prior we used. Columns 2–6: mass, age, initial hydrogen mass fraction and metallicity and mixing-length parameter. The estimates for all but the age are the Maximum A Posteriori (see text) with the associated 68% credible interval. The age was modelled with a Gaussian Mixture model and we give the mean, standard deviation and weight of each component.
