Olivine reflectance spectra and processing methods.(a) Final obtained olivine spectra(b) Smoothed spectrum of Fa70 P5×1mJ (c) continuum-removed spectrum of Fa70 P5×1mJ near 1.05 µm(d) continuum-removed spectrum of Fa70 P5×1mJ near 1.35 µm. The band center is defined as the wavelength with the minimum reflectance/continuum value calculated using the best-fitting polynomial function, and the band depth is defined as 1-Rminimum, where Rminimum is the reflectance/continuum value at the band center.
