Regression coefficients for the [s-/α] = m₁⋅age + m₂ ⋅ R_GC + m₃⋅ [Fe/H] + c relation. We show m₁ in the upper panel, m₂ in the second one, m₃ in the third one, and c in the fourth one. In the bottom panel, we present the correlation coefficients. In all panels, we use the following symbols: blue circles for the inner region, green circles for the solar region, pink circles for the outer region, and dashed black lines for the whole sample. The yellow region highlights the abundance ratios with Y, and the cyan region shows them with Ba.
