Bar as seen in selected transitions in units of erg cm2 s1 sr 1. No extinction correction is applied. Starting at the top, we show an image of the total AIB emission (i.e. sum of all AIB components in the 3.2–3.7 µm range). Following that, (from top to bottom) we show Pa γ, He I 2.058 µm, [Fe II] 1.644 µm, O I 1.317 µm, and [Fe III] 2.218 µm in the left column and H2 1−0 S(1), H2 2−1 S(1), H2 1−0 O(5), H2 0−0 S(9), and the continuum from the Gaussian decomposition at 3 µm (MJy sr−1) in the right column. We set the colour range from the bottom 0.5% to the top 99.5% intensity levels of the data for each map (across the entire NIRSpec mosaic), excluding values of zero, edge pixels, and the two proplyds (as well as the surrounding region of the proplyds for the continuum). White pixels inside the mosaic indicate values of zero reflecting issues with the data. The nearly horizontal red line indicates the NIRSpec cut and the nearly vertical red lines indicate from left to right the IF and the DFs (DF 1, DF 2, DF 3). The two proplyds are indicated by the circles. Across the entire NIRSpec mosaic, contours show the 52, 75, and 90% intensity levels of the data for AIB, 65, 80, 98% for Pa γ and He I 77.9, 90.2, 96% intensity levels for O I 1.317 µm and [Fe II] 1.644 µm, 87.7, 94.9% intensity levels for [Fe III] 2.218 µm, 60, 90, 98% intensity levels for ¾ (excluding H2 2−1 S(1), which uses 80, 90, 98% intensity levels), and the 50, 68, 85% intensity levels for the continuum at 3 µm. We note that a smoothing is applied to the [Fe III] 2.218 µm contour levels.
