Fig. 2


Singular values φi (left), singular vectors wi (middle) and the regularized solution Eq. (6) as a function of i (right). The lines in the singular value plot (left) indicate the regularization parameter λ that produces the solution with desired χ2 (dashed line) and with the additional positivity constraint (dash dot line). These values are from the regularized solution shown in Fig. 3.
