Contribution of the tSZ power spectrum in different cluster radial, mass and redshift bins. The plot is in terms of with units of [μK]² at 150 GHz. For these illustrative plots we have used the A10 pressure profile without modifications, and factored in the contribution from intrinsic scatter. The numbers in the square brackets mark the radial, redshift and mass bins for the individual curves. In the upper panel, the dashed lines only show the contribution from high-redshift (z> 0.5) clusters. The anisotropy power from cluster outskirts (r>r₅₀₀) becomes increasingly important at ℓ ≲ 3000.
