Notes. We include the cosmic time in Gyr at which 10%, 50%, and 90% of the total stellar mass are formed, as well as the metallicity [M/H]. The values shown correspond to the median values of the predicted posterior distributions, and the uncertainties to the standard deviations.
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.
