Kinematics of sub-populations. Angular momentum and orbital energy were computed in the same manner as in Matsuno et al. (2022b), with L_perp defined as $L_{\text{perp}}=\sqrt{L_x^2+L_y^2}$. Symbols follow that of Fig. 2. We also show the distributions of member stars of major substructures in Dodd et al. (2023) with contours and Eos members from Myeong et al. (2022) are indicated with black dots. For each substructure, contours encompass 50%, 80% and 98% of its members. Note that the distribution of Eos members is biased since Myeong et al. (2022) only included stars with high eccentricity.
