Left: position-velocity diagram along the major axis (PA of 115°) through the dynamic center. The cut was made from the SE (positive offsets) to the NW (negative offsets). Right: position-velocity diagram along the minor axis (PA of 25°) through the dynamic center, from the NE (positive offsets) to the SW (negative offsets). In both panels, the contours are at 2σ, in 2σ steps. The dynamic center is at (0, 0).
