Table 2

Quantitative results and the comparison with the actual sources in multisource case.

Source	Actual; position	Recon.; position	Location; error (mm)	Recon. density; (nW/mm^3)	RE of density	Recon. power; (nW)	RE of power
Source-1	(9.5,1,15)	(9.42,1.24,15.02)	0.49	1.06	6%	0.4916	6.12%
Source-2	(−9, 1.5,15)	(−9.29,1.5,15.06)	0.30	0.5713	42.87%	0.4416	15.66%
Source-3	(−9, −1.5,15)	(−9.30, −1.46,15.08)	0.31	0.6205	37.95%	0.4584	12.45%
