\caption{Computer simulation with space-variant PSFs 
(Fig.~\ref{fig:cluster_rec}): 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.\label{tab:labsim2_param}}
