The contribution from small scales on two-point shear analysis: comparison between power spectrum and correlation function
Harmonic-space cosmic shear analysis yields 2-3 times smaller model-choice biases in S8 than real-space analysis when pushing to small scales, with BACCO emulator plus TATT model giving the most consistent constraints between spaces.
