Notes. The first column shows the parameter and the second and third show the prior range adopted by KiDS and DES, respectively. Flat priors are indicated in square brackets, showing the edges of the prior and the Gaussian priors are shown as the mean ± the standard deviation on the parameter. The first 10 are cosmological parameters: As is the amplitude (defined at k0 = 0.05 Mpc−1) and ns is the spectral index of the primordial power spectrum. Ωb, Ωm, and ΩCDM are the density parameters for baryonic, total and cold dark matter, respectively, while Ων is the neutrino density parameter. Finally h is the dimensionless Hubble parameter. The next three parameters are the amplitude, AIA and redshift evolution, ηIA, parameters for the intrinsic alignment of galaxies and the baryon feedback parameter Abar (called B in H20). The final set of parameters capture the systematic effects, where mi is the multiplicative shear bias, σm is the dispersion of mi and Δzi is the additive shifts in redshift distributions for each bin. In the H20 setup the effect of m is applied to the data and its error is added to the covariance matrix (see Eq. (A.11)). Ac is the amplitude of the 2D additive bias explained in H20. The model used to evolve the non-linear matter power spectrum is shown in the last row.
