Fig. 3
All spectra are normalized to unity at 0.55 μm. Top: mean spectra of the two groups identified by Emery et al. (2011) among low-albedo Trojans compared with the mean spectrum of bright Trojans (from this study). Bottom: visible spectra of Hilda asteroids from Bus & Binzel (2002), Lazzaro et al. (2004), and the VNIR spectrum of (361) Bononia (Bus & Binzel 2002; Takir & Emery 2012) compared with the mean spectrum of bright Hilda asteroids (from this study).
