Figure 9: Gaussian fits for SO (bottom row) and CS (top row) in the centre positions of NGC 2071 (left column) and Orion A (right column). The residual spectra for Orion A show the result when the outflow component is subtracted. In the case of SO in Orion A an additional component due to the "hot core'' is subtracted (cf. Friberg [1984]). The subtracted components are shown as Gaussians
