To present the difference, we ran the algorithm for sucrose hydrolysis once again using the full spectra of the reaction mixture and a grid of values for κ mixture and κ components . As presented in Figure , the results are correct for small values of κ mixture and κ components . This is consistent with the interpretation of the parameters: small values of the penalties allow for easy removal of excessive signal. Clearly, if we compare the full spectrum of the mixture with the cut-down spectra of reagents, the large amount of signal is redundant.
