Profile cuts across the Bar at positions indicated in the small CH⁺J = 3–2 and OH 84 μm maps. The intensity of the lines have been normalized to the maximum emission in the Bar and the lines are not convolved to the same beam, so that the structures seen in the unconvolved maps are not lost. The distance is from the ionization front indicated by the peak of [NII] emission. The dashed part of the H₂ profile in the cuts indicates the slit seen in the map (see Fig. 7) and the positions of the cuts are indicated in the small maps next to each cut.
