Figure 4. - Total moment, subfault nrms, and data nrms (both based on reduced chi-squared values) as a function of the number of retained consecutive eigenvalues for the variable slip modeling. The total moment is the length of each subfault's slip vector, summed over all subfaults. The subfault nrms is an index of dispersion for the length of all subfaults' slip vectors. The data nrms is a similar index for the model residuals.
