Caption: Fig. 7.

Left: Line strengths of red giants in the calibration clusters from FLAMES data (Koch et al. 2006) vs. magnitude above the horizontal branch. Right: Metallicities of these globular clusters on the scale of Carretta & Gratton (1997), with the residuals of the best‐fit relation (eq. [6]) at the bottom. Solid and dashed lines indicate these best‐fit calibrations (eqs. [5] and [6]). All these measurements are based on the co‐added CaT.
