Table 1.
Simulation localisation error (mm) of mean reconstructed source centre. Source locations were calculated by taking the centres of fitted Gaussian distributions. Source A is the left-most source, and source B is the right-most source, as displayed in Fig. 3, Fig. 4, and Fig. 5. At each noise level, 30 samples of noisy measurements were generated. The location of each source was taken to be the location of the maximum value in a region (a sphere of radius 8mm) around the true source centre.
