The last feature we will demonstrate with these generic data is the possibility of the part-wise calculation of the RDF with the wsLSSA routine. In Fig. we can see a comparison of the pure wsLSSA for M = 16 and range of 1 ≤ r ≤ 4 Å (the same as in Fig. ) with the two RDFs of size M = 7 calculated for smaller ranges of 1 ≤ r ≤ 2.5 Å and 2.5 ≤ r ≤ 4 Å. As one can see, the two small-range RDFs look similar to the full-range one and the reference ones (RDF theor,num and RDF sim,num ). This means that the same routines can be used to look into smaller parts of the RDF curves. In the case of the rwsLSSA routine, we should bear in mind that the criterion given in Eq. 26 does not apply to not-full range data in r-space because of the Eq. 24 requirements. . Theoretical RDFs for tetrachloromethane (CCl 4 ), as obtained from the Eq. 28, and the rwsLSSA (M = 50) for the full s-range (Fig. ) and half of it. The optimal values of the regularization parameter were obtained from the criterion from Eq. 26. The colored areas around the curves, with corresponding color coding, represent the uncertainties given by Eq. 16. All curves were divided by their maximal value, corresponding to the Cl. . .Cl peak height. The damping factor in each case was γ = 0.001 Å 2 . . Theoretical RDFs for tetrachloromethane (CCl 4 ), as obtained from the Eq. 28 and simulated RDFs for tetrachloromethane (CCl 4 ), as obtained from the Eq. 28, and the pure wsLSSA in the full range from 1 ≤ r ≤ 4 Å and separated in two parts (1 ≤ r ≤ 2.5 Å and 2.5 ≤ r ≤ 4 Å). All curves are normalized to the same range of values. The damping factor in each case was γ = 0.001 Å 2 .
