Distribution of two different statistics computed on the simulations (blue histogram) and on the data (orange line). The first is the χ² statistic, where we compute χ² for the change in parameters between ℓ < 800 and ℓ < 2500, with respect to the covariance of the expected shifts. The second is a “biggest outlier” statistic, where we search for the parameter with the largest change, in units of the standard deviation of the simulated shifts. We give the probability to exceed (PTE) on each panel. For both statistics, we find that the observed shifts are largely consistent with expectations from simulations.
