Distribution of the 10th percentile in age for the clean final (green) and golden (gold) samples. In each panel, the top axis shows the corresponding H₀ values assuming a flat ΛCDM and a different value of Ω_m and z_f. The rows from top to bottom set z_f = 10, 20, ∞; the columns from left to right fix Ω_m = 0.25, 0.3, 0.35. The dashed and dash-dotted lines report the H₀ measurements from Riess et al. (2022) and Planck Collaboration VI (2020), respectively. Next to each one the percentage of stars in the final (green) and golden (gold) samples pointing to a lower H₀ at 90% CL (stat+syst) are reported.
