Correlation coefficient between multipole and rmsd distances for a subset of pairs closer in rmsd. Correlation coefficient as a function of the level of detail (highest multipole rank l
in the representation). In this calculations only six structures from the smaller set, those occupying the right side in Figure 4 are included: 1cja, 1nw1, 1j7u, 1cdk, 1csn and 1ir3. The distance between pairs of structures in this set are on average smaller than for the whole set in Figure 4.
