Chemical abundance ratio [X/Fe] as a function of the proton number Z. Measured [X/Fe] for P185129−300942, P185210−315413, and P185053−313317 are reported with blue, deep pink, and red circles, respectively. Theoretical [X/Fe] ratios from the STARFIT supernovae yields best fits are shown with solid lines coloured as the observed data. Arbitrary uncertainties (±0.2) on the theoretical yields are represented with shadow areas. NLTE-corrected [X/Fe] are used for some species (see Section 3.4). The names of the atomic species detected in this work are reported in the plot.
