Model dependent age posterior PDFs for the β Pic moving group derived from the three M stars (top) and from all four stars including V343 Nor Aa (bottom). The PDFs show well-constrained ages, and are consistent with the 24 ± 3 Myr age for the moving group as a whole derived by Bell et al. (2015), indicated by a vertical line and gray region for the 1σ uncertainty. By combining all the PDFs together we reach a final age for the β Pic moving group of 26 ± 3 Myr.
