Example of the analysis applied to A1795. Upper left: distribution of the ratio of the expected gas fraction (the dashed orange line represents R₅₀₀ and dashed cyan R₂₀₀) and observed gas fraction, F_i (solid horizontal lines, with errors represented by dotted lines; red represents R₅₀₀ and blue R₂₀₀) as a function of the slope, β (see Eq. (16)); the best-fit value is indicated by the yellow dot. Upper right: distribution of α as a function of radius with, overplotted in purple, the prediction from the model of α_turb in Angelinelli et al. (2020) and the expectations on the level of turbulence assuming η = 1/3 (green dashed line) and magnetic energy C_E = 0.05 (green dotted line; see Sect. 4 for details). Lower left: distribution of the turbulent velocity as a function of radius (see Eq. (22)). Lower right: distribution of the relative energy (Eq. (23)) as a function of radius. In red, we show the region used to constrain γ; R₅₀₀ and R₂₀₀ are indicated with vertical dashed and dotted lines.
