Constraints on the Dark Side of the Universe and Observational Hubble Parameter Data
Figure 3
Joint constraint on the energy density corresponding to the spatial curvature, , and the dark energy equation of state parameter, , by Stern et al. [26]. The large, irregular regions bounded by dark contours were from 5-year WMAP alone. The blue contours were obtained by adding constraints. Filled regions were obtained by further adding data. The application of data helps with breaking the degeneracy between and .
