Abstract
The MER Processing Function realises the merging of all the level 2 information and provides source catalogues containing object information relevant in the Euclid project. It starts from level 2 data provided by related OUs (VIS/NIR/EXT stacks or single epoch images, related PSF models and ancillary information); an object detection is performed in VIS and NIR, and the detected objects are combined. A multi-wavelength flux determination is performed on detected objects with suitable photometric techniques. The final output of the MER processing function is a catalogue of sources with unique identification number and multi-wavelength photometric information; the MER PF will also provide the required input (object identification number, position, fluxes, galactic extinction, effective wavelength of EXT passbands at objects’ positions) for photometric redshifts computation and spectra extraction. The Euclid SGS requirements specification 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. To ensure completeness and consistency with applicable documents, traceability and verification matrices complement the SGS Requirements Specification Documents.
