Comparison between VNIR spectra of the chassignite meteorites NWA 2737 (DD-AHT-067, DD-AHT-068, and DD-AHT-069 obtained from RELAB database (Pieters et al. 2008) and from Mandon et al. 2021) and Chassigny (DD-MDD-023 and MR-MJG-104 obtained from RELAB database), and Phobos and Deimos spectra from Fraeman et al. (2014). The spectra are normalized at 0.55 µm. The reflectance at 0.55 µm (r₅₅₀) is indicated in the figure for each laboratory spectra.
