Notes. Source of the metallicities: Harris (1996), transformed to the Carretta et al. (2009) scale. For V1, V29, and V48 in ω Cen we adopted metallicities from Gonzalez & Lambert (1997) converted to the current metallicity scale, based on a solar iron abundance by number of log ϵFe = 7.54 dex (Gratton et al. 2003). For the other TIICs in ω Cen (all BLHs), we adopted −1.61 dex, which is the metallicity of V48 (the only BLH with a spectroscopic estimate of the metallicity). This assumption agrees with the metallicity distribution found by Johnson & Pilachowski (2010) and Magurno et al. (2019) in ω Cen; moreover, it is well within the standard deviation of the metallicity distribution of this cluster. For NGC 6325, we adopted the iron abundance derived by Minniti (1995). We did not transform it to our scale because log ϵFe is not available, and the standard deviation is much larger (0.30 dex) than the correction.
