Kinematics and orbital-element properties of selected GCD stars. The color-coding of the symbols in the panels is based on their [Fe/H], while the gray background shading represents the kernel density estimation (KDE) model of the overlaid points. The distribution of the velocity component V_R vs. V_ϕ is shown in panel (a). The blue dashed line represents the approximate region for sources associated with the Gaia–Enceladus–Sausage in V_R vs. V_ϕ, based on Belokurov et al. (2018). The area occupied by disk-like stars is also highlighted with the black empty circle. The perigalactic and apogalactic distances, as a function of the orbital eccentricity, are shown in panels (b) and (c), respectively. The point sizes reflect their maximum vertical heights above the Galactic plane (﹩{{\rm{Z}}}_{{\text{}}{\max }}﹩), with decreasing size for decreasing ﹩{{\rm{Z}}}_{{\text{}}{\max }}﹩. Three black points at 2, 5, and 9.6 kpc are provided as a visual aid. Black up-tick symbols mark the stars with P–R orbital configurations (see text), while the “X” symbol indicates the star with a retrograde orbit.
