Distance Priors from Planck Final Release

Abstract

We present the distance priors from the finally released Planck TT,TE,EE+lowEPlanck~ \textrm{TT,TE,EE}+\textrm{lowE} data in 2018. The uncertainties are around 40%40\% smaller than those from PlanckPlanck 2015 TT++lowP. In order to check the validity of these new distance priors, we adopt the distance priors to constrain the cosmological parameters in different dark energy models, including the Λ\LambdaCDM model, the wwCDM model and the CPL model, and conclude that the distance priors provide consistent constraints on the relevant cosmological parameters compared to those from the full PlanckPlanck 2018 data release.
