OHD, GC, SN Ia, and BAO datasets with MCMC1 (left column) and MCMC2 (right) best-interpolating Bézier curves (blue curves) and 1–σ confidence bands for ℋ(z), 𝒟_A(z), ${(1 + z)}^{2} D_{A} (z)$ $(1+z)^2\mathcal D_{\mathrm{A}}(z)$ , 𝒳₃(z), and 𝒳₁(z) /(1+z) (gray bands), and 𝒜(z) and 𝒳₂(z) (green bands), compared to the ΛCDM paradigm from the Planck Collaboration VI (2020) (dashed red curves).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
