Caption: Figure 2.

Snapshot of an animation that shows the 3D distribution of ≈44,000 highly probable RRab stars selected by Sesar et al. (2017) from the PS1 ﹩3\pi ﹩ survey. The color indicates the angular distance of a star from the Sgr orbital plane (i.e., its Sgr latitude ﹩{\tilde{B}}_{\odot }﹩). The extended overdensities are dSph galaxies (e.g., Draco, Sextans, Ursa Minor).
