XCDM model: 68.3% and 95.4% confidence regions in the (Ωm, w) plane from QSO, BAO, CMB, and H(z). The left panel shows the QSO confidence region with the best-fit value for l only, while the right panel shows the confidence region including systematical uncertainties of l, β, and n. We note that CMB and QSO constraints are orthogonal, making this combination of cosmological probes very powerful for investigating the nature of dark energy.
