[0.3, 12]-keV XMM-Newton temperature map (in colour) computed from wavelet spectral-imaging (see Sect. 3.4). Contours of the MeerKAT 1.28 GHz image at the resolution of 40″ × 40″ (same as bottom panel of Fig. 3) are overlaid in white. The contours are drawn at ±0.1, 0.2, 0.4, 0.8 mJy beam⁻¹. The average rms in the image is ∼30 μJy beam⁻¹. The black areas are the subtracted individual sources. The magenta sectors show the regions of extraction of the temperature profiles in SC 1327–312 and SC 1329–313 (Sect. 5.2 and Fig. 15).
