Marginal mean and 68% CL error bars on cosmological parameters estimated when adopting different data choices for the Plik likelihood, in comparison with results from alternate approaches or model. We assume a ΛCDM model and use variations of Plik TT, EE, TE in combination with the lowTEB likelihood for most of the cases. The “Plik TT, EE, TE+lowTEB” case (black dot and thin horizontal black line) indicates the baseline (HM, ℓ_min = 30, ℓ_max = 2508), while the other cases are described in Appendix C.3.5. The grey bands show the standard deviation of the expected parameter shift, for those cases where the data used are a sub-sample of the baseline likelihood data (see Eq. (53)). All the cases are run with PICO .
