NIRSpec spectroscopic imaging data at 3.29 ± 0.015 μm (i.e. stacking channels at the peak of the PAH band). The disc is observed both in emission (lobes, red-yellow) and in silhouette (midplane, black) against the ambient field emission arising from the CH stretching mode of UV-excited astro-PAHs (blue).
