IntroductionΒΆ

The aim of the SIM Processing Function (developped by OU-SIM) is to produce homogeneous simulated data amongst the ECSGS in a coordinated way for integration, validation and verification of the complexe ECSGS framework. Simulations produced by OU-SIM also serve for the End to End performance validation of the entire Euclid mission.

Within the ECSGS, the SIM PF is primarily responsible for producing simulated level-1 data for the 3 Euclid channels: VIS, NISP-P and NISP-S. Further, the SIM PF produces simulated level-EXT data for DES, LSST, CFIS, WISHES, WHIGS, JEDIS and PANSTARRS surveys.

The SIM PF is divided into several Software Component, which are combined inside the SIM Pipeline. Interfaces between the different Processing Element of the pipeline are file-based. In the figure below, only the data interfaces used by each component are shown.

The detailed documentation of the SIM PF can be found in the Software Design Document on the Euclid Redmine.
