Maps of the different components obtained using PAHTAT to fit the observed mid-IR spectra of the NGC 7023 NW IRS spectral cube. Integrated intensities in the 5.5–14 μm range of the total emission (left map) and of the different band template components (central panels) are displayed. The map of the column density expressed in AV is also shown, as well as the flux in the H2 S(3) line (right maps). The black arrow shows the direction of the spatial cut studied in this work (Fig. 10). Contours of the total emission map are given in steps of 3 × 10-5 W m-2 sr-1 and are reported for reference in all the maps. The color intensity scales are in units of 10-5 W m-2 sr-1, while the column density is expressed in magnitude of visual extinction. Results for the other resolved PDRs can be found in Fig. 9.
