Caption: Figure 10.
Toomre diagram of UVW space motions corrected to the local standard of rest (LSR) for 74,066 Gaia DR2 stars within 100 pc of the Sun and having parallax errors <10% (Kirkpatrick et al. 2021b). Thin disk (light gray dots), thick disk (medium gray crosses), and halo (dark gray pluses) objects are marked, with halo stars falling outside the outer dashed circle (red) and thin disk objects falling inside the inner dashed circle (navy). Objects with measured radial velocities in Table 4 or Table 14 are shown in navy if lying in the thin disk velocity zone, yellow for the thick disk zone, and red for the halo zone. The six halo members are highlighted with black labels.
