Technical Summary:
We apply the technique of ``Ring Diagram'' (plane-wave k-omega) analysis to time series of Dopplergrams and/or photograms (at either resolution) covering one or more small comoving fields on the Sun. The power spectra of plane waves in the mapped regions are analyzed for displacement and distortion of the modal surfaces; these are parametrized, and the frequency variations for selected modes are inverted to infer the depth structure of velocity fields and sound speed averaged within each field.
