Fig. 2


Profile obtained from the APEX CO (2–1) observations. The profile is extremely broad (almost 800 km s-1 FWZI) and asymmetric, showing a pronounced blueshifted wing. The profile reaches velocities well outside the range covered by the regularly rotating large-scale gas disk. This is illustrated by the comparison with the velocities covered by the H I emission (indicated in gray in the plot, with arbitrary intensity scale). The blueward wing of the CO(2–1) profile covers velocities similar to those of the H I outflow detected in absorption.
