NIR spectral profiles of 23 asteroids normalized to unity at 1.0 µm. The spectra beyond 2.2 µm are truncated due to insufficient signal-to-noise. Note the spectra of objects (109640) and (112876), which exhibit comparatively redder slopes; as such, we identify them as possible outliers in the dataset. The gray zone marks the spectral region that is severely affected by atmospheric absorptions. The spectrum of Pallas is taken from Clark et al. (2010).
