Table 6.

Column 1: numbering of eigenvectors. Column 2: Eigenvalues (smallest at the first row and then increasing values). Columns 3, 4 and 5: The value of the cost function J(r* + δri) where the parameter vector r* is given in Table 4 and ri denotes the i–th eigenvector. Recall that J(r*) = 0 so the table illustrates how much the cost function is changed by changing the the parameter vector along and eigenvector of the Hessian matrix.
