1D posteriors for the w parameter within the Λ-GDM model. The green (dotted–dashed) curve is for the PPS data set, the black (solid) curve is for the combination of PPS and Planck lensing (Lens), the red (dotted) curve is for the PPS and Lens combination of data sets with the addition of HST prior, and the blue (dashed) curve is for the PPS, Lens, and BAO data set combination.
