Subarcsecond view of the Orion Bar PDR. Left: ALMA C2H N = 4–3 line emission (blue) and JWST F335M–F330M image (red), a proxy of the ∼3.3 μm AIB feature (Habart et al. 2024). For reference, we show the IRAM 30 m SDLS at α(2000) = 5:35:20.8 and δ(2000) = −05:25:17 with a dashed circle centered at the yellow cross. Right: zoom-in of a smaller field adding a Keck H2 v = 1−0 S (1) image (green) from Habart et al. (2023). Table A.1 shows the coordinates of the main DFs discussed in this work.
