[Ifeffit] More for dealing the LCF

9 Sep 2011

      I would be happy to get advices for LCF of EXAFS spectra, at the following
context:
1. Constraining the sum of components fractions to one –
 - when to apply?
 - Which factors should be considered at this context while working with soil
samples?
 - How would you suggest dealing the penalty when sum of components is different
than one in these heterogeneous soil samples (with unknown composition and
probably high effect of disorder)?

2. Any reason not to constrain all fractions to be positive?

Thanks,
Hana
