Spectral index as a function of the wavelength for the studied samples: X35 (upper left panel), X40 (upper right panel), X50A (lower left panel) and X50B (lower right panel). For each sample, the spectral index is displayed for different temperatures: 300 K (red), 100 K (green) ans 10 K (blue). The value of the spectral index was derived from a 6th order polynomial fit of the measured MAC.
