Notes. Median age and mass (μAge, μMass), and intrinsic age and mass spread (δAge, δMass) of the [α/Fe] > 0.1 population are reported together with their uncertainties (based on the 14th and 86th percentiles of the distribution). δMass is defined as twice the standard deviation of the Gaussian describing the intrinsic mass distribution, and δAge as the age range between μ − σ and μ + σ, with μ and σ the mean and standard deviation of the Gaussian in log10(age) (see Appendix B). ϵ describes the contaminant fraction as inferred from the mass distribution of both RGB and RC stars.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
