Notes. The abundance n(x) is given as fractional particle number of species x with respect to all elements. Statistical uncertainties (“Stat.”) correspond to Δχ2 = 6.63 and are 99% confidence limits. Systematic uncertainties (“Sys.”) cover only the effects induced by additional variations of 2% in Teff and 0.1 in log(g) and are formally taken to be 99% confidence limits (see Irrgang et al. 2014 for details).
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.
