Reflectances in MODIS bands as a function of wavelength in four selected representative pixels. See Fig. 16 for pixel identification. The relative reflectance spectrum of asteroid 2715 Mielikki taken from DeMeo et al. (2019) is shown for comparison. The same Mielikki spectrum recomputed for the optically thin dust situation (see the text) is provided as a dotted line. The last two spectra were normalized at 0.65 μm to the same value as the pixel 2 spectrum.
