[O I] emission of the total velocity range from –30 to 25 km s⁻¹ in contours overlaid on a map of 19 μm emission (FORCAST; Adams et al. 2015). Positions for which we show individual spectra of various lines and report the line integrated intensities in Table 2 (in a 15″ beam) are indicated with a cross and labelled 1–6. The angular resolution of the 19 μm emissionand the [O I] beam are indicated in the panel. For comparison, the 15″ resolution we used for PDR modelling is also given. Positions 1–6 do not always correspond to peaks in [O I] emission, but also to peak emission in high- and low-J CO lines (see text for details).
