Fig. 10: Inversion results. Relative differences between the squared sound speed in the Sun and a standard solar model as inferred from inversions of the frequency estimates computed with the mean-multiplet method (red) and the averaged-spectrum method (blue) from the MDI Medium-l data. The horizontal bars show the spatial resolution of the inferred values, while the vertical bars are the formal error estimates.
