The evaluations reported in this Technical Note are based on assumptions derived from the present knowledge of the subsystems architecture, scientific requirements and performances expected on the basis of previous experiments and results. This is a living document that has the function to report the details of the payload cables thermal analysis. It will follow the evolution of the harness design, characteristics and performances from the thermal point of view during the Ariel payload design consolidation process.
