Distribution of [Mg/Fe] (upper panel) and [Ca/Fe] (lower panel) as a function of [Fe/H] as in Fig. 11. Here we colour-coded the abundances of [Ca/Fe] and [Mg/Fe] according to the estimated uncertainty value. The colour-coding was fixed in both panels to the range of [Mg/Fe] uncertainties between 0.070.20 dex from black to red. The uncertainty contour of [Mg/Fe] is also shown in the background of both panels as a reference.
