Fig. 4

Eigen-decomposition analysis of PPP phenomenon for a neutron transmission data. The left figure shows the eigenvalues of the true and estimated DCM with two separated from the bulk. The right figure shows the eigenvector corresponding to the separated/dominating eigenvalue for both the true and estimated DCM, the latter of which is shown to align closely with the normalized data vector.
