First, we tried to apply the unregularized wsLSSA approach to the simulated dataset for the CCl 4 . For the visualization purposes, region for r was chosen as 1 ≤ r ≤ 4 Å, and only the equally distributed points were taken. The maximal number of RDF points allowed for the wsLSSA routine with this data was M = 16 (see Fig. ). One can clearly see two peak features, corresponding to the C-Cl and Cl. . .Cl distances, but there are also spurious slow oscillations, as those seen in the RDF theor,num and RDF sim,num (see discussion for Eq. 29).
