Notes. The solar abundances are from Caffau et al. (2011b) and Lodders et al. (2009). In column 11 (A(X)L) the 1D-LTE abundances from Lagae et al. (2023) derived with similar stellar parameters (Teff=5811, log ɡ=4.68), and in column 12 (A(X)C) the abundances from Caffau et al. (2012), with a similar Teff of 5811 and a much lower log g of 4.0, are given for reference.
