As explained by Claudio Proietti: "Cluster members are those scientists who participate in cluster activities. They may have or not an active role in leading and reporting specific items. They may have part of their time covered by W1/2 funds allocated to the cluster, both through earmarked and non-earmarked funding. They may also have their time covered by W3/Bilateral projects that are contributing to the Cluster."
