The Processing Functions are defined in the SGS Project Management Plan as self-contained processing units, i.e. the highest-level break-down of the complete SGS pipeline that can be achieved with units that communicate only with the help of the Euclid Archive System (EAS). The SDC-IT is responsible, as the primary SDC, for the coordination activity of the following Processing Functions: NIR, SIR, MER. The present Development Plan is co-written with OU-NIR, OU-SIR and OU-MER.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
