Fig. 3.


Intensity weighted velocity (moment 1) map of the 12CO J = 2−1 line, where the flux density in the channels has been clipped at 4σ. Contours show the continuum emission, with contour levels at [5, 10, 20, 40]σ. The beams of continuum (full ellipse) and CO line (empty ellipse) are shown in the bottom left corner.
