Element-abundance distributions of Berkeley 32 member stars with SNR ≥ 30 derived from the GES data. Panel (a) presents the [Fe/H] distribution, where different colors within each histogram bin denote the number of stars belonging to different evolutionary stages. Panel (b) shows the abundance distributions of the α elements Mg, Si, Ca, and Ti. The vertical dashed lines represent the median values of the distributions, while the quoted uncertainties correspond to the standard error of the median.
