Left: normalized temperature profiles for the CC clusters in the sample. Shaded areas show the error-weighted mean of the normalized temperature with its error (red) and rms dispersion (magenta) in 4 radial bins. The best fit to Vikhlinin et al. (2006) relation freeing the normalization is plotted as a blue solid line, while the blue dotted line and the blue dashed line represent the best fits to the relation in Eq. (3) (with ξ₀ = 0.45) and to Eq. (5) (for r > 0.15r₅₀₀), respectively. Right: normalized temperature profiles for the NCC clusters in the sample. Shaded areas show the error-weighted mean of the normalized temperature with its error (blue) and rms dispersion (cyan) in 6 radial bins. The best fit to Vikhlinin et al. (2006) relation (leaving the normalization free to vary), to the adaptation of the relation in Eq. (3) (with ξ₀ = 0.45), and to Eq. (5) are plotted as a red solid, dotted and dashed line, respectively.
