Fig. 4


3.5σ level in different velocity intervals offset from the systemic velocity (see inset). For HDO, the lowest velocities are towards the central region and slightly displaced into the blue-shifted outflow. Higher velocities are detected further out in both outflow lobes. The 465 GHz (for HDO) and 403 GHz (for CS and N2H+) continuum is plotted with black contours. The extent of the outflow is indicated in gray.
