Notes. The reference model is our best-fit base-ΛCDM cosmology from the Planck TT,TE,EE+lowE+lensing likelihood combination. The first set of rows show the results for the full binned Plik high-ℓ likelihood, while the second set of rows show the results from the coadded, unbinned CMB high-ℓ spectra. The last two rows show the results for the low-ℓ TT and low-ℓ EE likelihoods. The effective χ2 is defined as χeff = −2log(ℒ). The number of degrees of freedom (Ndof) is set equal to the number of multipoles. The last column lists the probability to exceed (PTE). The log(ℒ) value for the low-ℓ EE likelihood is normalized up to an arbitrary additive constant and so further entries are not shown in this case. Similarly, the non-Gaussian nature of the low-ℓ TT likelihood precludes us from displaying a PTE in this case.
