Posterior probability distribution function of the age spread of the high-α population in the sample (R1, see Table 1), resulting from the statistical model described in Appendix B. The cumulative distribution function is shown as a solid line and indicates that the 95% credible interval for the intrinsic age spread corresponds to δ ≲ 1.25 Gyr. Results from all the modelling runs are reported in Table 1.
