Planck: Planck data are spread into three different likelihoods following the original version of the Planck likelihoods.-
Planck lowT: likelihood based on the PR3 low-ℓ TT posterior distributions of measured$C_\ell$ fitted with a Wishart ($\alpha_\ell, \beta_\ell$ ). We then rescaled to the mock fiducial model with$\beta_\ell \longrightarrow \beta_\ell^{\rm mock} = (\alpha_\ell+1)C_{\ell,{\rm mock}}^{TT}$ . Multipole range available$\ell \in [2,29]$ . -
Planck lowE: Hamimeche&Lewis approximation using the Planck PR4 covariance matrix (LoLLiPoP) evaluated at the mock fiducial spectrum. Multipole range available$\ell \in [2,29]$ . -
Planck high-ℓ (TT,TE,EE): Gaussian likelihood for TT , TE and EE power spectra, with the full covariance matrix from the PR3 Planck-lite likelihood (marginalised over foreground parameters). Multipole range available$\ell \in [30,2508]$ .

LiteBIRD: Wishart likelihood for TT , TE, and EE spectra, using beam-deconvolved noise spectra including foreground residuals after ILC and an effective sky fraction fsky ∈ {0.7, 0.8} from E-mode group. Multipole range available$\ell \in [2,2500]$ . -
Simons-Observatory: Wishart likelihood with noise curves including foreground residuals. Multipole range available$\ell \in [127,7979]$ . -
CMB-S4: Wishart likelihood with noise curves including foreground residuals. Multipole range available$\ell \in [127,10000]$ .
