Our sample spans a narrow range of metallicities, peaking at $-1.07\\pm 0.06$, and exhibit abundance ratios of [Si,Al/Fe] that are as extreme as those observed in Galactic globular clusters (GCs), and Mg is slightly less overabundant. In almost all the sources we used, the elemental abundances were re-determined from high-resolution spectra, which were re-analyzed assuming LTE. Thus, we compiled the main element families, namely the ","authors_text":"Alan Alves-Brito, Angeles P\\'erez-Villegas, Annie C.
