Ages from Nissen et al. (2020) compared to our determinations for the 72 stars in Nissen et al. (2020). The two violet dots (HD 20766 and HD 20807 stars) are the components of the visual binary star ζ Reticuli. The yellow dots are the stars characterized by a noisy PDF that made either the determination of the ±1σ or the maximum of the problematic. Given this issue we do not display the error bars for these objects.
