Graph of b₁ for the FFP10 dataset. In panel a, the observational curves are presented in yellow, and the curves corresponding to the average of simulations are presented in gray. Error bands corresponding to (1σ : 4σ) are also drawn. Panel b: significance of the differences. The dataset exhibits milder deviations than the NPIPE dataset in general, but there are mildly significant deviations at 2.77σ, at scales and thresholds where the NPIPE dataset shows strong deviations as well.
