Final Report of TPOS 2020

The Third and Final Report of TPOS 2020 has been fully endorsed by the Steering Committee as the conclusion of the TPOS 2020 Project. This report builds upon the First and Second Reports (released in 2016 and 2019, respectively), provides an update that resolves issues where possible, and sets the stage for our successors. The Final Report provides the foundation for the future evolution of the arrays: describing remaining unresolved issues and a governance structure that will provide the necessary scientific advice and coordination among the implementing agencies.
