Figure 4.

The 2D anisotropy functions (a) for ${\hspace{0.17em}}^{125}\mathrm{I}$ are compared at 1 and 5 cm with reference published data by Weaver; ⁽²⁴⁾ values for ${\hspace{0.17em}}^{192}\mathrm{I}\mathrm{r}$ (b) are compared with published data by Granero et al. ⁽²⁰⁾ Maximum differences for two seeds are limited to 2% except at small angles is reached up to 8% (TG43U1 for 6702 is reported typically 10%). The MC statistical uncertainties are at most 2.5%.
