Comparison between the 24 ground-based spectra (Binzel et al. 2001; Vilas 2008, 2012; Moskovitz et al. 2013; Lazzaro et al. 2013; Perna et al. 2017) and disk-average spectrum observed by ONC-T/Hayabusa2 at phase angles between 18.5° and 18.7°. All spectra are normalized to unity at 0.55 μm. The red points indicate the binned spectra by 0.02 μm and error bars are standard deviation inside of each bin. The ground-based observations are shown, ordered according to S/N values.
