[Sr/Fe] as a function of [Fe/H] (upper panel) and [Sr/Ba] as a function of [Ba/Fe] abundance ratios (lower panel) for our sample of stars (red star symbols). The cyan star with a black open circle indicates the star CES1237+1922. Grey open squares are stars in the Milky Way halo and crosses are stars in dSph (yellow) and UFD galaxies (blue) in the literature. Literature abundance ratios are taken from: François et al. (2007, Milky Way halo), Norris et al. (2010, Bootes I), Frebel et al. (2010, Ursa Major II, Coma Berenices), Simon et al. (2010, Leo IV), Hansen et al. (2012, Milky Way halo), Ishigaki et al. (2014, Bootes I), François et al. (2016, Canes Venatici I, Hercules), Ji et al. (2016), Reticulum II), Roederer et al. (2016, Reticulum II), Mashonkina et al. (2017b, Milky Way halo, Sculptor, Fornax, Sextans, Ursa Minor, Bootes I, Ursa Major II, Leo IV), Reichert et al. (2020, Draco, Sculptor, Ursa Minor, Sextans, Sagittarius, Fornax, Ursa Major II, Bootes I, Segue 1, Triangulum II), Sitnova et al. (2021, Segue 1, Triangulum II, Coma Berenices, Ursa Major II), and Skúladóttir et al. (2024, Sculptor).
