X-ray coverage. The orange colours show the XRISM image after the particle-background subtraction and vignetting correction (Figure 2c from Suzuki et al. 2025). The FoV of XRISM is denoted with a white box. The blue contours are the same as shown in black in Figure 1, outlining the H.E.S.S. emission. Existing coverage by Chandra and XMM-Newton is shown with pink dashed and yellow dotted lines, respectively.
