Notes.In the lowest stellar mass bin 9.5 < log (M⋆) < 10, we set the value of σ which is not constrained. Systematic uncertainties are not included. We consider that a systematic uncertainty of + 0.1 dex could affect SFR measurement (see Sect. 2). Assuming a systematic uncertainty of ±0.1 dex in the stellar mass, we obtain a systematic uncertainty of 
in the log (sSFR∗), the median and the averaged sSFR estimates.
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.
