Stellar density and kinematics of Sgr projected on the sky plane upon COM subtraction. Stellar density is shown by black contours. From left to right, the color maps indicate the error-weighted average velocity of v_x, v_y, and v_z inside Voronoi cells of ∼1000 stars. The Voronoi cells are the same in the three panels. A black arrow indicates the sky-projected bulk velocity of the COM. Coordinates were derived from Equation (8) and represent physical distances in kiloparsecs. Velocities were obtained from Equation (9) and are the Cartesian components of the velocities projected over the axes. A grid aligned with the stream coordinates system (Law & Majewski 2010) is also plotted.
