Left:two-dimensional marginalized constraints on Ωm,0 and H0 obtained by fitting the η measurements from VIPERS data with a flat ΛCDM model. Contours are plotted for ℒ−ℒmin < 2.3,6.17. In this case, Ωb h2, ns, σ8, and σ12 are fixed to the value quoted in the text (i.e. they have a Dirac delta prior). We also draw curves corresponding to degeneracy along the loci Ωm,0h2 = const. (dotted line) and Ωm,0h = const. (dashed line). Right: the same but in the plane [Ωm,0, ns].
