Folded spectra for GTI 1 obtained with XMM-Newton/EPIC-pn (orange), NuSTAR/FPMA (red) and FPMB (dark blue), and XRISM/Resolve (light blue). Solid lines show the best-fit model and corresponding ratio in the bottom panel computed as data/model. A zoom in the Fe region is shown to highlight the resolution capabilities of Resolve. For plotting and readability purposes, the NuSTAR and XMM-Newton data are not displayed in the zoomed window and the XRISM/Resolve data are binned to a minimum of 150 counts/bin.
