Same as Fig. C.1, but for the three different observables in our analysis. The fits to the distributions are used to determine the number of degrees of freedom for each observable, which are in turn are used to determine the reduced χ² values for each of them. Note that the χ² distributions are not a result of maximising the posterior for that section of the mocks. The vertical lines show the χ² values from the real data, matching in colours with the histograms.
