Equatorial plane velocity profiles of the ICM in the α_turb = 0 models of the clusters of our sample. Left panel: Ratio between the gas rotation velocity and velocity dispersion (measured in the equatorial plane) as a function of the cylindrical radius normalized to the virial radius, r₂₀₀ = 3M₂₀₀/[800πρ_crit]^1/3, computed using the median value of M₂₀₀ for each cluster. Right panel: Gas rotation velocity as a function of the cylindrical radius in physical units. In both panels the dashed lines are the median profiles of the individual clusters (as indicated in the legend), whereas the gray band represents the interval between the 16th and 84th percentiles of the distribution of the profiles of the entire sample of clusters.
