[Mg/Fe] and [Si/Fe] versus [Fe/H] diagrams for Patchick 126 (cyan points), NGC 6388 (open blue diamonds), NGC 6441 (open black squares), NGC 6838 (M71) (open violet pentagons), NGC 6553 (open orange triangles), and bulge field stars (grey points) at R_G < 3 kpc. The APOGEE-2 bulge stars from Abdurro'uf et al. (2022) were selected using precise galactocentric distances from the StarHorse catalogue (Queiroz et al. 2023). We rescaled the abundances derived by Abdurro'uf et al. (2022) using ASPCAP to match those obtained with BACCHUS, applying systematic offsets of 0.11, 0.07, and 0.05 for [Fe/H], [Mg/Fe], and [Si/Fe], respectively, as determined by Fernández-Trincado et al. (2020).
