Ring Diagram Analysis
 In the so-called Ring Diagram analysis area of Solar doppler maps at different latitudes and longitudes are first tracked at their rotation rate and remapped. Each area thus produces a data-cube of remapped Doppler maps.

 These data-cubes are then 3D Fourier transformed. Cuts at given temporal frequencies of the resulting 3D power spectra looks like rings in the kx-ky plane that are distorted by the undelying flows at different sub-photospheric depths.
