Notes. While we see no evidence that systematic effects in polarization are biasing parameters in the base ΛCDM model, a conservative choice would be to use the parameter values listed in Col. 3 (i.e., for TT+lowP+lensing). Nuisance parameters are not listed here for brevity, but can be found in the extensive tables on the Planck Legacy Archive, http://pla.esac.esa.int/pla; however, the last three parameters listed here give a summary measure of the total foreground amplitude (in μK2) at ℓ = 2000 for the three high-ℓ temperature power spectra used by the likelihood. In all cases the helium mass fraction used is predicted by BBN from the baryon abundance (posterior mean YP ≈ 0.2453, with theoretical uncertainties in the BBN predictions dominating over the Planck error on Ωbh2). The Hubble constant is given in units of km s-1 Mpc-1, while r∗ is in Mpc and wavenumbers are in Mpc-1.
