nuvalidation_uhp.yaml

# Paper-validated CLASS ultra-high-precision (UHP) spectroscopic profile
# used for the neutrino-sector validation, Archidiacono et al.,
# arXiv:2405.06047v1. Uses a deeper neutrino-perturbation treatment
# (l_max_ncdm=40, exact/no fluid approximation) than the photometric
# class/nuvalidation_hp.yaml tier, at higher computational cost.
