Table 2.
Typical uncertainty sources encountered in PFNS measurements are tabulated with special emphasis on shapes of correlations. “ND” was used as an abbreviation for nuclear data.
| Unc. | Cor(Expi,Expi) | Cor(Expi, Expj) i ≠ j |
|---|---|---|
| δc | Diagonal | None |
| δb | Gaussian | Facility and method dependent |
| δm | Gaussian anti-correlated | Facility and method |
| around 2T | dependent | |
| δε | Gaussian | Depends on ε determination |
| δa | Gaussian | Gaussian |
| δτ | Full | 0 |
| ND | From libraries | From libraries |
| δt | From TOF →Eout transformation | 0 |
| ΔL | From TOF →Eout transformation | 0 |
| Δω | Dependent on shape difference | Sample/ method dependent |
| between main and impurity PFNS |
