Notes. The column log(age/yr) (τ) indicates the (log-)age estimated by the isochrone fitting procedure. The column τexp indicates the expansion ages determined by using the formula τexp = 1/(γκ) for the groups for which it is possible to determine the expansion parameter κ. The number of stars N is different than in Table A.1 because by applying the kinematic modelling we remove kinematic outliers from the groups.
