Notes. The first set of rows gives 68% limits for the base-ΛCDM model, while the second set gives 68% constraints on a number of derived parameters (as obtained from the constraints on the parameters used to specify the base-ΛCDM model). The third set below the double line gives 95% limits for some 1-parameter extensions to the ΛCDM model. More details can be found in Planck Collaboration IV (2020).
