Figure 18: η-parameterization. 1 and 2σ marginalized probability regions obtained assuming constant γ and w (red solid curves) or assuming the parameterizations (1.8.6View Equation) and (1.8.2View Equation) and marginalizing over η and w1 (black dashed curves); marginalized error values are in columns σ γmarg,2, σwmarg,2 of Table 9. Yellow dots represent the fiducial model, the triangles stand for a f (R ) model and the squares mark the flat DGP.
