Variation of (top) DM (β_DM) and (bottom) stellar (β_*) velocity anisotropy as a function of galactocentric radius normalised by the respective half-mass radius. Solid and dashed lines represent the median values of the isolated and tidally bound galaxy sub-samples, respectively. The 25th and 75th quartile regions are shown with shaded regions: solid-filled regions are for the isolated sub-samples and crossed diagonal lines are for the tidally bound ones.
