abstract: >
  A Python package for tomographic filtering of seismic mantle structure
  (vS or vP) using the resolution matrix R of the LLNL-G3D-JPS model.
  Given a velocity model on the LLNL grid, llnltofi applies the resolution
  operator via a single sparse matrix-vector multiply R*m = m' and returns
  the filtered result.
