Top left: Based on our MCMC procedure for the selection of (w₀-w_a, Ω_Λ) combinations consistent (at 2-σ level) with the considered cosmological probes, we show as the average Ω_Λ as a function of (w₀-w_a) coloured contours. The colour-code is shown by the bar in the bottom right of the figure. Top right: For combinations (w₀ ≥ −1, w_a ≥ 0) considered here, we show the values of Ω_m and σ₈ consistent (at a 2-σ level) with the considered cosmological probes. The colour-code refers to the average values of Ω_Λ corresponding to each combination, as shown by the bottom bar. Bottom left: Probability distribution of Ω_Λ resulting from our MCMC procedure for the combinations (w₀ ≥ −1, w_a ≥ 0) considered here.
