Notes. For each species, we show the mean value and the standard deviation. We compare with values estimated with ASPCAP/APOGEE DR17 and with previous high-resolution studies on this cluster Johnson et al. (2018) and Valenti et al. (2011). The Solar reference abundances are from Asplund et al. (2005), except for Ce and Nd, which is taken from Grevesse et al. (2015).
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.
