[Ifeffit] Rbkg value

Hello everyone,


In removing background, most literature suggests Rbkg value of 1.0 because
below this represents mostly noise and low freq components not part of the
scattering effect.  In using Feff and viewing the individual paths
calculated a number of them have paths near 1.5 A, therefore meaning that
they have some contributions very close to 1.0 A and below in R space due to
phase shift.  Has anyone modeled materials which contain these rather short
Reff and how did you decide what was scattering and noise?


Thank you all,
