Abstract

We present the distance priors from the finally released Planck~ \textrmTT,TE,EE+\textrmlowE data in 2018. The uncertainties are around 40% smaller than those from Planck 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 ΛCDM model, the wCDM 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 Planck 2018 data release.
