Impact of lifting priors on ΛCDM cosmological parameters. We show results obtained when lifting the TT inter-frequency parameters and described in Sect. 3.3.4 (dashed red), when lifting the SZ amplitude priors described in Sect. 3.3.1 (dashed blue), and when lifting the dust amplitude priors in TT and TE, while allowing the dust-amplitude values in EE to vary freely (dashed green). We also show the impact of letting all of the nuisance parameters vary freely (keeping only a prior on the overall calibration yP, as given in Eq. (39), solid magenta). The baseline TTTEEE+SimAll case is in solid black. In all these cases, shifts with respect to the baseline are smaller than 0.5 σ.
