Fiducial choice of cosmological parameters within ΛCDM used for the forward simulations to test the signal and noise modelling for KiDS-Legacy-like. The given cosmology is equivalent to S8≡σ8[(Ωb+Ωc)/0.3]1/2=0.82. The parameters are set in accordance with the constraints from KiDS-1000 (Asgari et al. 2021b), while σ8 is set to be the mid-value between KiDS-1000 and Planck (Planck Collaboration VI 2020).
