Notes. Δ(Teff) etc. are the abundance changes corresponding to +1σ changes in each of the three stellar parameters, and their sum; Δobs combines the observational uncertainties discussed in the text, and ΔTot is the total error estimate for each element.
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.
