Figure 51: Supernovae and CMB constraints in the (Ω 𝒟0 m,n) plane for the averaged effective model with zero Friedmannian curvature (filled ellipses) and for a standard flat FLRW model with a quintessence field with constant equation of state w = − (n + 3)∕3 (black ellipses). The disk and diamond represent the absolute best-fit models respectively for the standard FLRW model and the averaged effective model.
