Fig. 3

Upper panel: H2O 179 μm intensity cut along the L1448 flow, at PA 164°. The normalized intensity is integrated over a width of 30″ perpendicular to the cut. The location of the C(N) source is taken as the reference for the offsets. Bottom panel: normalized intensities of the 179 μm H2O line and continuum around the L1448-C source, along the same cut direction as above.
