Results of the spectral modeling. The results are presented for the H and K parts (top and bottom part of the figure, respectively). The top panels show, from the bottom to the top, spectra of Pluto converted in albedo obtained at SEEL of 5, 41, and 111°, respectively. They are associated with their best-fit models, in purple, green, and red (shifted for clarity by +0, +0.05 and +0.1, respectively). The bottom panels present excursions of the models when greater than the observational error defined at 1σ level. ^∗ Position of metallic lines and their assignment (see Lancon & Rocca-Volmerange 1992, for more details).
