Mass biases (1 − b_HE, X) and (1 − b_HE, SZ) are shown as a function of the slope of the gas density, 𝒟, and of the pressure profile, β_P. Empty and filled circles have the same meaning as in Fig. 13. Magenta points are well-fitted clusters with the lowest clumpiness values, the cyan points show those with the highest clumpiness values. The vertical lines represent the value 𝒟 = 5.5 and β = 6 which are approximately the 75^th percentiles of the values of the two slopes. All quantities are measured in 3D so each cluster appears only once.
