Metadata package supporting DOI:10.1103/PhysRevD.106.023521 (COLAB, NCN OPUS)

This record provides a metadata package supporting DOI: 10.1103/PhysRevD.106.023521. It documents dataset provenance, access conditions, and high-level reproducibility notes. Primary input data: Copernicus Complexio (COCO) simulations (CDM and WDM flavours). Access is consortium-only at the time of this deposit, and the simulation products are not redistributed here. Access contacts: Wojciech A. Hellwing ([e-mail], CFT PAN, Warsaw) and Sownak Bose ([e-mail], ICC Durham University). Core simulation references: Hellwing et al. 2016 (COCO CDM, DOI: 10.1093/mnras/stw214) and Bose et al. 2016 (COCO WDM, DOI: 10.1093/mnras/stv2294). Funding: NCN OPUS COLAB (UMO-2020/39/B/ST9/03494).
