Abundance ratios of the hydrostatic (upper panel) and explosive (lower panel) α-elements in the GCs of our extended sample. The blue and red points indicate accreted and in situ GCs. The black squares show disc GCs, and the green triangles show bulge GCs from the literature. The Pearson correlation coefficient and two-tailed probability are listed. Only Mg is used to represent the hydrostatic species in field stars.
