Extended Data Fig. 4: XRISM/Resolve spectra from detector regions 1-3 and their best-fit models.

For each region, we show a broad-band spectrum from 3–11 keV and a detailed view of the Fe XXV He-α triplet on the right. Pink, orange, blue, and green curves represent the best-fit models of the NXB, the combined scattered ICM, the ICM, and the AGN components, respectively. The cyan curves on the right show the Fe XXV He-α w line Gaussian component, while the red curves show the total models. Residuals normalized by the statistical errors, i.e., (data-model)/error, are displayed in the lower panels with two different binning schemes: black points correspond to the binning with minimum significance \({\sigma }_{\min }=3\), while purple points show the binning with \({\sigma }_{\min }=20\).
