Inner halo populations in kinematic and dynamical diagrams. Top panel: Lindblad diagram. The contours represent the 33, 66, 90, 95, 98, 99, and 99.9% cumulative distribution of the populations disentangled with the TITANS and GALAH metal-poor stars. The regions and stars corresponding to the Gaia-Enceladus, Splash, and Erebus populations are highlighted. Here, the TITANS that have disc dynamics are also shown for completeness. Mid panel: Toomre diagram. Symbols and colors are the same as in the top panel. The region of disc stars, selected following Helmi et al. (2018), is delimited by the dashed line. Bottom panel: eccentricity vs. maximum distance from the Galactic plane (Z_max). Symbols and colors are the same as in the other panels.
