We then reconstruct the corresponding history of the Universe background expansion and fit it to type Ia supernovae data, putting constraints on $(Ømega_m,0,\sigma_8,0)$. The results obtained are consistent with the concordance flat-$Łambda$CDM model and General Relativity as the gravity theory given the current quality of the inhomogeneity growth data.
