Notes. N is the number of degrees of freedom, χN2 is the χ-squared value of the comparison, and P(χN2) is the probability distribution (a proxy for the confidence level) obtained from standard χ2 tables (Beyer 1991). For Case A, we considered all available observed values. For Cases B and C, we disregarded, respectively, the first and the first two elements that yielded the worst (highest) ![$ q_i=\frac{([X_i/\rm{Fe}]-[X_i/\rm{Fe}]_{\mathrm{obs}})^2}{\epsilon_i^2} $](/articles/aa/full_html/2025/11/aa56363-25/aa56363-25-eq8.gif)
