Release 4.2 of this document is based on the results and metrics from the Scientific Challenge 8 runs. It extrapolates these figures under assumptions clearly stated: for the prelaunch phase, simulation production plan, end-to-end scenarios, and operational rehearsal tests; for the post-launch phase, reprocessing ratio and simulation scenarios. This document highlights the most stringent assumptions and uncertainties about these figures, assesses the consequences of this processing budget on the SGS architecture, identifying bottlenecks, risks and action plans; it matches the infrastructure procurement strategy for the different stakeholders (SDC’s) of the Euclid Consortium with the infrastructure requirements derived from this document. This document is a living document: its origins are in the Preliminary Requirements Review with raw inputs and rough estimates from OU/SDC’s. This document will continue to be updated as necessary.ELETTRONICOenResearch reportFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation::PE9_17 Instrumentation – telescopes, detectors and techniques
