The PF is divided into two main processing blocks: the pre-processing, with the task of removing most detector signatures from the data; and the spectra extraction, with the task of locating and extracting the spectra from the NISP spectroscopic data, and to produce fully wavelength and flux calibrated one and two-dimensional spectra. In parallel to this “scientific” pipeline, within the SIR PF there is also a calibration pipeline, which is a collection of specific processing elements with the task of reducing the calibration observations and to prepare the calibration data needed by the scientific pipeline. The Euclid SGS requirements specification process produces the Euclid SGS Requirements Specification Document and a set of Requirements Specification Documents for specific SGS products such as the Processing Functions. The present document is part of this set of documents. To ensure completeness and consistency with applicable documents, traceability and verification matrices complement the SGS Requirements Specification Documents.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
