First (top) and second (bottom) moment of the flux distribution of the Hα emission obtained with the Cube2Im function in CubExtractor, representing the v_shift and σ_vel maps. The gray contours show the morphology of the extended (up to ≈5 kpc) blueshifted CO (3–2) molecular outflow, detected by B19, at the emission levels of 1, 4, 8, and 10 mJy. The black circles and contours are the same as in Fig. 7.
