Three-dimensional stellar kinematics of the O/B stars and emission line stars (smaller arrows). The arrows denote the proper motions, colours signify different radial velocities v_z. The black cross indicates the position of Sgr A*. The coordinates show the offset to Sgr A* in equatorial coordinates, the numbers at the top and left denote absolute equatorial coordinates. The Galactic plane is plotted as a blue dashed line, and the line of nodes of the clockwise disk with Ω = 96° is shown as a red line. The green dot-dashed line illustrates the projected rotation axis of the clockwise disk.
