CO absorption line map of velocity, and velocity dispersion (left, and right, respectively) obtained by using the full data cube. Both, velocity and velocity dispersion are in units of km s^-1. The coordinates are centred on Sgr A* and along the Galactic plane with a position angle of 31.̊40. The plus sign marks the position of Sgr A*. The velocity is in the local standard of rest, Galactic north is up, Galactic east is left.
