The sky distribution of the stars in the new coordinates is showed in the left panel. The shadow region represents the coverage of the new stream with −45° < ϕ₁ < 65° and |ϕ₂|< 5°. The stars with arrows represent the stars with RV from LAMOST (red) and DESI (magenta). The arrows represent the tangential velocities with Solar motion corrected. The right panel shows the number distribution of the stars along the latitude ϕ₂ with longitude −45° < ϕ₁ < 65°. The dashed line represents the fitting results with a Gaussian distribution.
