Resulting H₀ from different mass models for a range of possible Δt_1b, 1a measurements with 10% uncertainty from SN Encore in a flat ΛCDM cosmology with Ω_m = 1 − Ω_Λ = 0.3. The median values of H₀ are shown as solid lines, while the shaded regions indicate the 1σ uncertainty. Left panel: All model predictions overlaid, as indicated in the legend. Right four panels: Subset of the model predictions plotted in the same style as in the left panel, for better visibility.
