Caption: Figure 4.

Toomre diagram of UVW space motions corrected to the local standard of rest for 74,066 Gaia DR2 stars within 100 pc of the Sun and having parallax errors <10%. Thin disk (blue dots), thick disk (black crosses), and halo (green circles) objects are marked, per the text. WISE 1534−1043 (orange diamonds) is shown at 13 radial velocities ranging from −300 to 300 km s⁻¹, in steps of 50 km s⁻¹. All values suggest a rare member of the halo.
