Notes. Values derived from single lines are marked with a colon. The standard deviation is given in parentheses, and was assumed to be 0.5 dex when the measurement was obtained from a single line only. The last column contains solar photospheric abundances that were taken from Asplund et al. (2021).
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.
