Euclid spectroscopy quality-control project for spectral extraction, contamination, observational diagnostics and data-quality limits, designed to make measurement quality and failure modes explicit and reproducible.

Euclid stellar-shape and PSF diagnostic for image-quality assessment, weak-lensing calibration and shape-measurement consistency, using reproducible analysis of observational data and explicit quality limits.

Euclid galaxy-morphology consistency study comparing structural measurements, shape estimates and catalogue agreement while auditing imaging systematics, data quality and reproducibility across morphological observables.
