Kinematic properties of the various structures identified in this work. The dark red and purple dashed lines indicate the extent of the nonrotating and retrograde high-energy RMEs, respectively. The solid yellow line indicates the extent of the low-energy RME, and the dashed light-blue line surrounds the isotropic halo background. The light-red ellipse indicates the location of the Nyx Stream, the green and blue dashed lines show the extent of Splash and disk stars, respectively. Contours in the bottom row show the 95%, 75%, and 50% levels of stars within the VRM, Nereus, and Cronus selections in the top row. The stars in the center of the top panels have low velocity, and therefore lower energy since the stars in the solar neighborhood have similar potential energies.
