Euclid SGS NIR Software Design Document

Version 0.7 reviewed by ESA at the Euclid SGS Design Review (2017) Version 1.1 submitted as reference document for the Euclid SGS Implementation Review (2021) Version 1.2 submitted as reference document for the Euclid SGS Readiness Review (2022) This software design document provides a description of the software architectural design and a detailed design of the NIR Processing Function (PF). It presents the high-level architectural overview and the architecture and design of each NIR PF software component. It also includes the traceability matrix from each software component to the requirements. This document covers the functional architecture of the NIR PF. For each NIR pipeline processing step, a high-level description of the algorithm is provided together with references to the relevant documents which include more detailed information. This document explains what the software does and how, but it does not explain how to operate it; for that, refer to the software user manual.
