Notes. N indicates the number of regions used. σ [X/H] represents the scatter of the abundance determined from different regions, when at least two are measured for the ion.

(a)

[X/Fe] computed against Fe i for neutral species except O i, against Fe ii for ionized species and O i.

(b)

All [X/Fe] computed against Fe ii.

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.
