Fig. 9
Variability in the optical properties across the subjects at the different measured locations. The solid lines in the top two rows depict the mean absorption and scattering spectra respectively across all the subjects, while the shaded region represents the standard deviation (SD) across means for individual subjects. The bottom row compares intra-subject versus inter-subject variability. The red lines stand for the coefficient of variation (CV) across measurements per site on a single subject, whereas the black lines show the CV across all the subjects. In both the cases, the solid lines represent the CV for absorption while the dotted ones correspond to scattering.
