Note.
The synthetic spectra were based on 1D Local Thermodynamic Equilibrium (LTE) model atmospheres calculated using MARCS models (Gustafsson et al. 2008) and the Solar abundances from Asplund et al. (2005), except for Ce II, Nd II, and Yb II, for which we have adopted the Solar abundances from Grevesse et al. (2015).
