Comparison of various X/Fe abundance ratios predicted by the SN_Ia yield models used in our top five “SN_Ia model” best fits (Table 3). Upper and lower horizontal axes mark respectively the odd- and even-Z elements. For comparison, we also show the relative (i.e. normalised to 1) observational uncertainties on the X/Fe ratios derived (i) in this work using the X-IFU (12 ratios, as tracked by our input simulations, C and N are not shown here), and (ii) using ∼300 ks of Hitomi/SXS (in synergy with ∼200 ks of XMM-Newton/RGS) exposure (Simionescu et al. 2019).
