BLUR3: Eigenvalues of the array of stacked PSFs centered at zero are shown in the top, for both direct (left) and inverse regularized (right) cases. Main (direct) deformable kernels are represented in the first column, their interpolation functions are in the second column, inverse regularized deformable kernels are in the third column and their interpolation functions are in the last column.
