Notes.Top part contains dwarf stars from the comparison sample, while lower part shows giants from the second comparison sample. Details and subscripts are described in Table 3.

(FS)

The synthesised LTE abundances can be found in the First Stars papers; dwarfs from Bonifacio et al. (2009, B09), and giants from François et al. (2007, F07).

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.
