Radial anisotropy profiles of the two chemically defined populations. Left panel: σ_PM,tan/σ_PM,rad as a function of radius for the Al-poor and Al-rich stars. The shaded bands mark the corresponding global values from bottom left panel of Fig. 3. The HST-based measurements of the MS-I and MS-II populations from Bellini et al. (2018) are overplotted for comparison. Right panel: combined sample, compared to the oMEGACat profile from Häberle et al. (2025).
