Maps of the individual components of the 5.7 µm band decomposition. The lower panel is analogous to Fig. 5. The top panel is a legend illustrating the subcomponents labeled A, B, and C. The light gray line shows the ATM spectrum data, the solid black line is the best fitting total model, and the dashed line shows the sum of all other components (continuum and wings of nearby Drude profiles), to which the three 5.7 µm components were added.
