Figure [Moulik & Ekstrom, 2014] (a) Anisotropic velocity variations (vSH − vSV)/vS in S362ANI+M and SAW642ANb. Average anisotropy at each depth, as specified in < >, has been removed to eliminate the contribution from the reference models that are different in the two models. (b) Correlation between S362ANI+M and SAW642ANb calculated up to spherical harmonic degrees 2 (dashed line) and 8 (solid line). (c) Correlation between isotropic and anisotropic variations in S362ANI+M (solid line) and SAW642ANb (dashed line) calculated up to spherical harmonic degree 8. The dotted lines in (b) and© indicate the 410- and 650-km discontinuities and the shaded areas indicate correlations lower than –0.3 and higher than 0.3.
