Notes. Abundance ratios are scaled to the solar values of A(C)⊙ = 8.46, A(N)⊙ = 7.83, A(O)⊙ = 8.69, A(Mg)⊙ = 7.55, A(F)⊙ = 4.40, A(Fe)⊙ = 7.46, and A(Ce)⊙ = 1.58 (Asplund et al. 2021). Typical uncertainties of our derived stellar parameters are ±100 K in Teff, ±0.2 dex in log g, ±0.1 dex in [Fe/H], ±0.1 km s−1 in vmic, ±0.1 dex in [C/Fe], and ±0.1 dex in [N/Fe]. The values given here for vmac are derived from the H band.
