Position on the sky, heliocentric distance, proper motions, line-of-sight, and Galactocentric radial velocities of the stars from the structure that we identified in Fig. 5 (red symbols). The light-blue and purple points are the stars identified as part of the Sagittarius stream by Ibata et al. (2020) and Vasiliev et al. (2021), respectively. Lower panel: another structure, highlighted by the orange rectangle, stands out around RA ∼ 25°, and is made up of stars that have clearly distinct galactocentric radial velocities from both the Sagittarius stream and the contaminating background stars (mostly originating from the Gaia-Enceladus-Sausage) shown by the black contours in each panel. The stars from this structure, which appears to be the Cetus stream, are shown by the orange stars in the other panels; they also form a distinctly visible structure in μ_α, * and μ_δ, *
