Top: maximum number (choosing the value of ΔR that gives the maximum value) of sigmas of significance detection of different metallicity distributions in the subsamples with R > R1, |z| < 5 kpc, and R > R2, |z| ≥ 5 kpc, respectively, such that ⟨r1⟩≈⟨r2⟩. Bottom: parameters N1, N2, and Δ R corresponding to that detection.
