To investigate the possibility of mapping anisotropic S velocity structure into the P velocity model, we have performed an inversion with only spheroidal modes. The resulting P and S models are highly consistent with models obtained based upon the entire data set, suggesting that we are indeed modelling isotropic P and S heterogeneity, rather than an anisotropic signal.

Comparison of models based upon a data set using both spheroidal and toroidal modes and using only spheroidal modes. Correlation of shear velocity models from the two data sets are shown in red and comparison of compressional velocity models are shown in blue.
