Relation between the distance to the seed and corresponding angle for every pair of elements of a cluster (excluding the seed). Specifically, rmsdij + rmsdik, for all xj, xk ∈ C1(θr), j, k ≠ i, where xi is the seed of C1(θr) and θr has the values 0.12 nm (A) and 0.17 nm (B), against the angle φ between the vectors xij and xik, where xij = xj – xi.
