Top panel: LTE abundances calculated using MOOG and the EWs from Cayrel et al. (2004), Roederer et al. (2014), and Spina et al. (2016). Lower panel: non-LTE corrected abundances (from the LTE abundances in the upper panel). The LTE and non-LTE corrected abundances (in A(K)), are shown in Table A.1. In both panels we also show three different GCE models: in black the model from Kobayashi et al. (2011); in dashed blue and orange the models from Prantzos et al. (2018) without and with yields from massive rotating stars, respectively.
