Spectral model of the system Chariklo and rings with the rings edge-on. The red line represents the best-fit to the spectrum (see Table 4 for details). The shaded area represents a set of the 30 best fits to the spectrum. The relative reflectance is normalized to the albedo value of each model at 0.55 μm for the fit; this albedo value is allowed to vary between 0.035 and 0.041 (see text for details).
