  1. The table compares the home base of countries found for each community using three different criteria: simple |dQ|, |dQ| * S, where S is the node strengh and internal link density Wint. Results do not vary significantly with the only exception of the Nordic cluster (IX) that, when we use |dQ|, has its center in Denmark instead of Finland (|dQ| * S and Wint).
