(a) Projected gas temperature map for the central 0.6 × 0.6 h⁻¹₇₁ Mpc² (8.77 × 8.77 arcmin²) region, along with the 68 per cent error map (b). These are calculated from the XMM–Newton MOS1+MOS2+pn data. Partial elliptical annuli defined in the north, east, south and west sector regions are shown in (a), which are used to extract both the Chandra and XMM–Newton spectra analysed in Section 3.2.
