Overlay of the [O i] 63 μm PACS observation on a Spitzer/IRAC 8 μm image of the Orion Bar. A 4 × 4 raster map – 16 overlapping footprints – was performed (see Sect. 2). An example of a footprint with its 5 × 5 spaxels is illustrated on the top left of the figure together with their dimensions. The map covers the region before and behind the Bar (toward θ1 Ori C).
