(A) Peak location distributions from using the maxima of the individual spectra (B) Porphyrin basis spectra for unmixing tests. CpIII and the new PpIX634 are based on pig brain phantoms. The old PpIX spectra (labeled PpIX620 and PpIX634) are from Black et al. (2021). The new and old PpIX634 match very well, so the new PpIX634 and the CpIII should be directly applicable to our existing human data.
