Comparison of the energy and momentum (left and center panels, respectively) derived from the analysis of the [O i] emission with the corresponding CO values from Plunkett et al. (2013), as listed in Table 3. The CO and [O i] momenta (empty and filled circles, respectively) are plotted against the embedded-source bolometric luminosities in the right-most panel. In the same panel, filled and empty stars correspond to the east-west outflow of source IRAS 2A.
