Differences between the derived Fe abundances using the best-fit multi-T model and those using the 1T model, plotted against the ICM temperature. Error barsare the result of uncertainties in the ICM temperature derived from the 1T model, including systematic uncertainties of 10%. Upper and lower panels correspond to Fe abundances derived from F_FeHeK/F_3.5−6 and F_FeHK/F_3.5−6, respectively. The indications of the colors are the same as in Fig. 4.
