Left: Deconvolved, deprojected, 3D temperature profiles of the EXCPReS sample, scaled by R₅₀₀ and the spectral temperature in the [0.15 − 0.75] R₅₀₀ region, colour-coded by total mass. The best-fitting analytical model (Eqs. 2–5) is overplotted. Right: Scaled 3D profiles of the EXCPReS sample (points with error bars) and best-fitting model (orange), compared to the best-fitting model to the scaled temperature profile of the REXCESS sample (blue). Envelopes indicate the radially-varying intrinsic scatter term. The dotted line shows the best-fitting model to the local cool core sample of Vikhlinin et al. (2006).
