Model metallicity (blue line) as a function of the projected radius $\widehat{R}$ (the profile in the extrapolation range is dashed). The Ghirardini et al. (2019a) measurements are the black dots, with vertical and horizonthal error bars corresponding to the statistical uncertainties in the spectral analyses and to the extent of the radial bins. The XRISM/Resolve pointings extend from the center out to the vertical line.
