Table 2.

Comparison between FMC and perturbation model (${\mathrm{P}}_{\text{MODEL}}$) for case #2. The maximum differences between ${\mathrm{P}}_{\text{MODEL}}$ and ${\mathrm{P}}_{\text{FMCWS}}$ for ${\hspace{0.17em}}^{192}\mathrm{I}\mathrm{r}$ and ${\hspace{0.17em}}^{125}\mathrm{I}$ are less than 3.7% and 4.7%, respectively. The MC uncertainties are at most 2.3%.
