Differences between the SOE algorithm predictions and the MC calculations of the secondary gamma origin emission versus the number of iterations of the SOE algorithm for the positions of (a) the maximum emission, and the falloff to (b) 90%, (c) 50%, and (d) 20% of the maximum. Results are shown for SOE reconstructions using the following numbers of gammas and VPP values, respectively: 1M and 2 mm3 (green circles), 4M and 2 mm3 (purple squares), 1M and 1 mm3 (cyan triangles), 4M and 1 mm3 (red diamonds), 1M and 0.5 mm3 (blue crosses), and 4M and 0.5 mm3 (orange stars).
