Spatial and global kinematic properties of the Al-poor and Al-rich populations. Top panel: spatial cumulative distribution functions of the two families compared to the global sample. The p-values from a Kolmogorov-Smirnov test, which compares each family to the global sCDF, are also shown. Bottom panel: global anisotropy ratios σ_PM,tan/σ_PM,rad, σ_PM,tan/σ_los and total intrinsic rotation amplitude A_tot for the Al-poor, Al-rich, and combined samples. The figure shows that the Al-rich family is more centrally concentrated and more radially anisotropic than the Al-poor family, while both share a comparable intrinsic rotation amplitude.
