[Ifeffit] Restrain

Hi all, i have query regarding restrain. suppose i have single scattering path which is equal to lattice parameter. Now i also have multi-scattering path with Reff equal to the same single scattering path. Now my question is, Is it correct to constraint the all path of same reff to equal delt_r, Because i think in magnitude they must lie on same R but different in phase (different frequency component). thanks -- *​* *A.
