Scientific paper

Helioseismic holography is an important method for measuring physical conditions in the solar interior. Synthetic data is a powerful tool for validating the methods of local helioseismology. Here we show some example inversions of surface-focusing holography measurements of synthetic data sets. We show that Born-approximation based inversions of phase-speed and ridge-filtered measurements yield models that are consistent with the true sound-speed structure in some simple test cases. This work is supported by NASA contracts NNH09CE41C and NNG07EI51C.
