Fig. 6


Observed (plus symbols) and modelled (solid and dotted lines) profiles along the cut shown in Fig. 4 (see Sect. 5) measured with respect to the distance to the exciting star θ1 Ori C. Observed and modelled fluxes are convolved to the 158 μm PSF, where the dotted line includes an offset due to background emission (see text). The first four panels compare for each line the observed convolved profiles with a Cloudy model, where this has been scaled to the peak of the [O i] (145 μm) emission. The bottom panel compares the normalized model profiles. In this panel, the solid dots represent the position of the reference points in the adopted cut (Fig. 4a).
