Reduced equivalent width ⟨ W′ ⟩ from CaII triplet from Saviane et al. (2012a) against calibrated [Fe/H] from this work. The blue solid line is the quadratic function fitted to the data (Eq. (6)) and the red dashed line is the cubic function fitted by Saviane et al. (2012a) to calibrate their ⟨ W′ ⟩ S12 to the Carretta scale. Fitted curves are shown only in their respective valid ranges.
