  1. Real? Real? Inversions

  2. Real? One of the biggest challenges for inversion is to take seriously the issue of what is the level of confidence in features in the solution

  3. Issues • It’s time inverters started working harder – discoveries are to be made in the subtle signatures in flows and structure. • Beat down the systematics • Make better assessment of input errors • Properly take into account error correlations

  4. Issues • It’s time inverters started working harder – discoveries are to be made in the subtle signatures in flows and structure. • Beat down the systematics • Make better assessment of input errors • Properly take into account error correlations • Need to do better with near-surface • Incorporate high-l data • Kernels need to take into account the way freqs are measured • How to incorporate local helioseismic data: 3D models in C.Z. ? • Make higher-order representations of “surface term”
