Notes. R0.55 is absolute reflectance at 0.55 µm. S1 to S6 are spectral slopes calculated within 0.4–0.5 µm, 0.5–0.6 µm, 0.8–0.9 µm, 1.1–1.2 µm, 1.1–1.4 µm, and 1.6–1.8 µm bands, respectively. The Qingzhen (enstatite) refers to the area richer in enstatite in Qingzhen meteorite, while Qingzhen (metal) refers to the area richer in metal in Qingzhen meteorite. -ung means the meteorite is ungrouped.
