In color scale, the Spitzer IRAC 8 μm image of the NGC 7023 NW PDR (Werner et al. 2004). The dark lines demarcate the region in which AKARI-IRC data were obtained, the white rectangle represents the Spitzer-IRS field of view. The star represents the position of HD 200775. The insets represent the AKARI and IRS beam sizes. AKARI spectra between 2.8 and 3.9 μm are shown to the right. They correspond to the positions P1-P4 that are marked as black dots on the map.
