Heat map representing the parameter uncertainty of S_n(Z, N − 1) (relative to HFB-24 values) as a function of S_n(Z, N) uncertainties (relative to HFB-24 values) for each BFMC combination selected in Case 2 (10643 combinations). The subplots use the same axis and are separated by isotopic chains to show the correlation for each of them. Each frame is 500 per 500 bins and each bin is color-coded to the number of combinations in it.
