Projected temperature profiles. Left: First round results (R1), using only the Suzaku data. The grey shaded regions denote the azimuthally-averaged temperature measurements. The dotted and dashed lines show the radius of r₅₀₀ and r₂₀₀ respectively. Right: Comparison between different rounds of azimuthally averaged measurements. All three rounds of spectra were extracted from the same annuli but shifted by 0.5′ in this plot for illustration purpose. The abundance is fixed to 0.3 beyond r₅₀₀ (Werner et al. 2013; Urban et al. 2017).
