Comparison of the spectra of Makemake from the literature in the 0.70 − 0.92μm range. From top to bottom: in orange, the spectrum from Licandro et al. (2006b) taken in 2005; in blue the spectrum from Tegler et al. (2007) taken in 2006; in black the spectrum corresponding to phase 1 from this work taken in 2008. All the spectra are normalized at 0.75 μm and shifted by 1.0 in relative reflectance for clarity. The dotted lines denote the center of the absorption bands of pure methane ice.
