Difference of average Betti numbers b₀ (left) and b₁ (centre) and peak counts (right) between cosmo-SLICS and SLICS. Left and central panels: x-axis represents the respective filtration level t, which runs from the minimum to the maximum value of the S/N aperture map. The lines are colour-coded by the value of S₈ in the respective cosmo-SLICS (see Table A.1). The lines shown here are averages over all mock realisations of the full survey footprint (10 for each cosmo-SLICS node, 126 for SLICS).
