Comparison between ONC-T and NIRS3 reflectance spectra (after applying the updated calibration) acquired at a similar time and for the same region of the Ryugu surface, and ground-based observations from N. A. Moskovitz et al. (2013) and L. Le Corre et al. (2018). N. A. Moskovitz et al. (2013) spectrum was smoothed using a Savitzky–Golay filter with a polynomial of degree 3 and a window of five points. All spectra are normalized at 2 μm.
