Table 1.

Typical uncertainty sources encountered in PFNS measurements are listed dependent on their specific measurement type. Also, estimates of typical uncertainty ranges are provided in case this information cannot be derived otherwise for uncertainty-quantification purposes. “ND” was used as an abbreviation for nuclear data.
