Four groups of asteroids with their respective best-fit meteorite analogs. The meteorite spectra were obtained from the RELAB library (Pieters & Hiroi 2004; Milliken 2020), and the asteroid spectra are from this work. A representative asteroid from each group is shown in color, while the remaining asteroids in the same meteorite-matching group are displayed in gray. In the legend of the top-left plot, the values 63–125 µm and <63 µm indicate the grain sizes of the corresponding meteorite spectra. The yellow zone marks the spectral region that is severely affected by atmospheric absorptions.
