Position-velocity plot of the CO(2–1) obtained from a cut taken perpendicular to the radio axis and passing through the core (PA = 52°). On the larger scales, the emission shows the overall velocity gradient of the CO and shows the high velocity dispersion gas redshifted compared to the systemic velocity at the location of the core as a separate component. Contour levels: −0.18, 0.18–2 mJy beam⁻¹ in steps of 0.18 mJy beam⁻¹.
