Elements of the correlation matrix of the observed ratios r₀₂(n) and rr_{01 / 10}(n). Lines (columns) 1 to 8 correspond to the r₀₂(n) ratios (n is in the range 17−24). Lines (columns) 9 to 16 correspond to the rr₀₁(n) ratios and lines (columns) 17 to 24 correspond to the rr₁₀(n) ratios (n is in the range 16−23). As expected, there are strong correlations between some of the data, in particular between the rr₀₁(n) and rr₁₀(n) ratios that have the same n value or values of n that differ by one unit.
