Top: entropy profiles obtained from the three different methods described in Sect. 4.5. The dashed magenta line represents the best fit obtained on the K_NFW data using Eq. (9). Bottom: entropy profiles rescaled by K₅₀₀. The dashed magenta line represents the best fit obtained on the K_NFW data using Eq. (12). The green lines represents the prediction from Voit et al. (2005). The dashed pink lines are the best fit using Eqs. (9) and (12). The vertical dotted and dashed line represents the location of R₅₀₀ and R₂₀₀, respectively.
