2D likelihoods for the power spectra amplitudes at ℓ = 3000 using our MCMC algorithm, compared to the results from R12. The plot shows the tSZ power spectrum () using the template of Shaw et al. (2010), and the two CIB components, its Poisson contribution () and the clustered component (). The filled colored contours show the 1, 2, and 3σ constraints from the SPT analysis. The black solid contours show the constraints from our MCMC sampling, where the other foregrounds are held fixed together with the cosmological parameters.
