ΔY (upper panels) and ΔBa (lower panels) as a function of ΔO for the whole survey sample (except for NGC 7078). The sample was divided into three metallicity bins: [Fe/H] < −1.80 dex (metal-poor; left panels), −1.80 dex < [Fe/H] < −1.10 dex (metal-mid; mid-panels), and [Fe/H] > −1.10 dex (metal-rich; right panels). The respective Spearman coefficient and p-value are reported on each panel.
