Prediction of the different models, ΛCDM, spline reconstruction, and coasting reconstruction with SNIa intrinsic luminosity evolution, for the growth of matter perturbations f σ₈ observable. The predictions have been computed using the best-fit values for the parameters obtained from the fit of the combination SNIa+BAO+CMB computing r_d explicitly. Therefore, it is not a fit to the f σ₈ measurements. We follow the same color legend as in the previous figures: black for ΛCDM, red for the spline reconstruction, and green for the coasting reconstruction.
