Figure 8
Calculated (Icalc) versus numerically simulated (Iobs) diffraction intensities for the Fibonacci chain with phasons (a) and after phasonic correction in the form of (b) the multiplicative standard Debye–Waller factor or (c) the additive term (sum of Bessel functions). The phason occurrence probability is [\alpha = 5\%]. The standard phasonic Debye–Waller factor used in a refinement procedure favors strong reflections, for which a clear mismatch is visible in (a). This is the reason why the fit for weak reflections is completely wrong in graph (b). The statistical approach does not cause these effects.
