Comparison of the posteriors of cosmological parameters for the γΛCDM model (shown in orange) and γwCDM (shown in blue). The constraints from the standard ΛCDM model presented in G24 (ΛCDM in gray, and wCDM in black) are plotted for comparison. The γΛCDM model prefers a lower value of σ₈ and a higher value for Ω_m. This is explained by the anticorrelation between σ₈ and γ and the positive correlation between Ω_m and γ.
