JWST NIRCam composite image of the Orion Bar located in the Orion molecular cloud (Habart et al. 2024). Red is the 3.35 μm emission (F335M NIRCam filter), blue is the emission of Paα (F187N filter subtracted by F182M filter) and green is the emission of the H₂ 0–0 S(9) line at 4.70 μm (F470N filter subtracted by F480M filter). The ${\mathrm{C}\mathrm{H}}_3^{+}$ and CH⁺ emission is detected in the protoplanetary disk and in the dissociation fronts. The white box represents the area where the NIRSpec and MIRI spectroscopy mosaic overlap. The green box corresponds to the apertures used in this paper to derive spectra. We use the aperture from Peeters et al. (2024) for DF3 and the aperture from Berné et al. (2024) for d203-506. The dashed black circle corresponds to the largest beam of Herschel-HIFI.
