Prediction for the tSZ power spectrum amplitude from the A10 model, but using both the WMAP7 and Planck best fit cosmological model parameters. The higher predicted amplitude from the Planck cosmology comes primarily from the higher values of σ₈ and Ω_b. The shaded regions around the best-fit models are obtained using the respective parameters chains for these two parameters. The higher sensitivity of Planck clearly provides tighter constraints, although will require more drastic changes to the ICM pressure profile than we considered in this paper.
