Mass bias and ratio between turbulent and thermal energy in the clusters in our sample. Top: Ratio between the turbulent and the thermal energy computed based on the σ_T, int/T values and under the assumption that the isobaric fluctuations are dominant. The dashed horizontal lines are computed for different Mach numbers using the following equation: . In the right y-axis, we provide the mass bias b estimated within R₅₀₀ through Eq. (14). The empty squares indicate the values of E_turb/E_th (and b) after the correction accounting for the underlying power spectrum (see the text for more details). Bottom: Distribution of the values of the hydrostatic bias. In gray (blue), we show the b values before (after) accounting for the integration of the power spectrum between some characteristic scales (see text in Sect. 4.3). Dotted lines indicate the means of the distributions.
