Scaling relation between the gas velocity dispersion inside the aperture and the root mean square for the kSZ. The integration aperture is Rvir. The fit corresponds to RMSkSZ = A(σv/σ0)B, where σ0 = 300 km s−1 is the pivot velocity dispersion and the shown error corresponds to a 16 − 84 confidence interval. The fitting slopes (α) and errors are shown below the figure legend.
