Integrated ¹²CO emission in different velocity intervals, where Δυ = 2km s^-1 (inset in each panel). The centre velocities (υ − υ_sys) for each bins are indicated in the respective panels. High-velocity gas (Δυ> 5km s^-1) is detected in four different spots along the outflow axis (indicated with black arrows in the upper right panel). First solid thick contour is at 3σ and the 2σ level is indicated with a dashed line.
