Claim 2:
3. The method according to claim 1, wherein in step c) the contribution of the scattering signal for |φ(t)|<ε, wherein ε≤π to the total scattering signal S over an oscillation cycle (|φ(t)|≤π) is made small by determining the coefficients An such that

r=√{square root over (|∫−ε+εH2(φ)dφ|)}/√{square root over (|∫−π+πH2(φ)dφ)}|<δ,

wherein

H(φ)=ΣnAn cos(nφ)  (II)

and δ=0.1, preferably δ=0.01 and most preferably δ=0.001.
