Figure 3

(Color online) The fit of the luminosity distance – redshift relation for the LWRS brane-world models with dark radiation, (including the ΛCDM model for Ω d = 0). There is no assumption for Ω ρ (0.15, 0.35), its preferred value 0.225 being determined from the supernova data, together with the preferred value 0.040 of Ω d . The contours refer to the 1-σ and 2-σ confidence levels and both are centered on the LWRS model with the values given above. The local minimum represented by the ΛCDM model is at Ω ρ = 0.275. Both the global and local minima are marked. The white area in the lower left corner represents the forbidden region of the parameter space for z = 3.
