Observed H₂O, CO₂, and CO ice optical depth mapped images of the disc at 3.0, 4.26, and 4.67 μm derived from the NIRSpec image at those wavelengths calculated relative to the reference continuum intensities taken at 3.7, 4.32, and 4.72 μm, respectively. Over-plotted white contours show the flux intensity at the band centres, normalised to their maximum in the map. The last contour is at 5% from the maximum.
