Samples from the distribution of the dark energy parameters w0 and wa using Planck TT+lowP+BAO+JLA data, colour-coded by the value of the Hubble parameter H0. Contours show the corresponding 68% and 95% limits. Dashed grey lines intersect at the point in parameter space corresponding to a cosmological constant.
