Fig. 2.

Left plot shows differences as defined in (1) between DGRF-2005 candidate models and their mean model M as a function of the index of the spherical harmonic coefficient (running from etc indexed 1, 2, 3, 4, 5, etc). Right plot shows the Huber robust weighting factor i w α , where 1.0 indicates full weight 0.0 indicates zero weight, also as a function of the spherical harmonic coefficient.
