Red curve: distribution of obtained with a model describing the observations well. The distribution follows a reduced χ2 law. The value (see the text for a definition of this quantity) is marked by the dashed line and is obtained considering p = 5% in Eq. (8). Blue curve: example of a distribution when the model does not describe the observations well. 90% of the are higher than the . For both curves, we consider k = 100.
