Table 5: Computer simulation with space-variant PSFs (Fig. 7): magnitudes of the stars reconstructed with the space-variant BB (sv. BB) and the conventional BB (conv. BB) methods, and the differences ($\Delta $) between the reconstructed and original star magnitudes. The values show that the deviations from the true magnitudes are on average $\sim $4 times smaller in the reconstruction obtained with the space-variant BB method.
