Notes. (a)An evolutionary correction has been applied to the C abundances (Placco et al. 2014). (b)Only unmixed giants have been selected, using the surface abundance of Li as a diagnostic of the mixing (Spite et al. 2005). (c)Nitrogen and oxygen have been corrected for 3D effects (Spite et al. 2005).
