Table 1.

Coordinates of simulated point-like sources positioned according to the NEMA norm. Each source is characterized by a different mean lifetime of ortho-positronium

Position	Coordinates [cm]	Simulated oPs mean lifetime [ns]
1	(1, 0, 0)	2.0
2	(10, 0, 0)	2.4
3	(20, 0, 0)	2.8
4	(1, 0, 75)	2.2
5	(10, 0, 75)	2.6
6	(20, 0, 75)	3.0
