Supplementary material

The supplemental material contain seven files:

• Two files for the new pointwise evaluation (mean values and correlations) shown in Figures 14 and 15,

• Two files (mean values and correlations) for the pointwise evaluation matching Mannhart’s evaluation the closest shown in Figure 13,

• Two json databases representing the input data to the before-mentioned evaluations,

• The smoothed version of the new pointwise evaluation is given in Figure 14.

Fig. 15. Evaluated correlations matrix after (left) and before (right) enforcing normalization on the evaluated PFNS. (a) Normalized. (b) Not normalized.

Fig. 16. C/E ratios of SACS, ⟨σ⟩, calculated with Mannhart’s versus this evaluations to experimental data are compared to values from Table 18 in [48].

The evaluated files are simple text files with the first column containing outgoing energy (MeV), the second column the PFNS, and the third column relative uncertainties in %. The spectra are not normalized, and thus the PFNS has arbitrary units. The correlation files contain for each row, a row of the covariance. The smoothed evaluation contains only a column with outgoing energy and PFNS that is now given in 1/MeV as it is normalized.

The json experimental database contains the input data as used for the evaluations. Each dataset is contained in one dictionary that contains outgoing energy, mean values, covariances along with metadata key words extracted from the literature, EXFOR and documentation of thoughts of the authors.

These files should help guarantee reproducibility of the evaluation.
