Figure 4
Microscopy images and infrared maps of hair sections from the Mende and Marseille mummies. The plain white square on the microscopy images corresponds to the beam size. Note the absorbance variation of the amide bands for both hairs, and of the amide I [\alpha/\beta] ratio for Marseille hair. For the alkyl and amide maps, the signal is normalized to the maximum value and each step of the contour plots corresponds to a variation of 10% of this maximum. For the amide I ratio map, the signal is set to zero outside the hair contour.
