Goodness-of-fit of the flat ΛCDM cosmological model to each of the single and joint probe combinations with cosmic shear, galaxy clustering and galaxy-galaxy lensing (GGL).

Notes. We list the χ2 value at the maximum of the posterior, the number of degrees of freedom (d.o.f.) of the data, the effective d.o.f. of the model, and the probability to exceed (PTE) the measured χ2 value, assuming the total d.o.f. are given by data d.o.f.−model d.o.f. The effective d.o.f. of the model are estimated following Joachimi et al. (2021) and Raveri & Hu (2019), accounting for the impact of priors and non-linear dependencies between the parameters.
