Extended Data Fig. 2: Parabola-fitting results for CE4_0015 and CE4_0016 1-μm and 2-μm absorption-band positions.

Extended Data Fig. 2

a, Reflectance of CE4_0015; the positions of the 1-μm and 2-μm bands are 949.2 nm and 1,985.9 nm, respectively. b, Reflectance of CE4_0016; the 1-μm- and 2-μm-band positions are 995.1 nm and 1,984.9 nm, respectively. The 2-μm-band centre assignment is tentative because of its weak absorption. The red and blue lines represent the wavelength ranges used for the parabola fitting of the 1-μm- and 2-μm-band centres, respectively.
