Notes. The first five parameters are the standard cosmological parameters. Other parameters are nuisance parameters introduced by Hildebrandt et al. (2020) to account for various effects associated with cosmic shear analysis. The KV450 best-fit values are extracted from the primary Monte Carlo Markov chain, which is publicly available at5. The Planck best-fit values correspond to the TT,TE,EE+lowE+lensing results with the Plik likelihood (Table 1 of Planck Collaboration VI 2020).
