Justitia compared to CCs. As with the asteroids in Figure 2, the similarity between Justitia’s spectrum and that of the meteorites is evident even with the 2.5–2.9 μm data gap. All of the meteorites are of metamorphic grade 2, save the Orgueil sample, which was metamorphic grade 1 before heating. The Orgueil spectrum is from K. Amano et al. (2023); the ALH 83102 and LON 94101 spectra are from H. C. Bates et al. (2021). The Tagish Lake spectrum was obtained from the RELAB database, with sample ID MT-MEZ-011 (PI: Zolensky).
