The raw spectral measurements and fits. The spectra with tissue scattering and water absorption = "+w", with added blood = "+b", with added PPIX = "+p". The y-axis is the ratio tissue/standard. The x-axis is wavelength.
The absorption spectra and the components based on fits. The bilirubin and PPIX components are shown as one curve with two broad Gaussians, labeled as "PPIX". The oxy- and deoxy-hemoglobin curves are labeled "oxyHGb" and "deoxyHGb".
The reduced scattering coefficient.
