The HMI Ring-Diagram Pipeline: Recent Developments and Future Prospects
Abstract
The HMI ring-diagram pipeline produces tracked Doppler data cubes at three different size and time scales, their power spectra, two independent types of "mode" (ridge) fits to the spectra, and inversions of fit parameters measuring the mean near- and sub-surface flows. Ancillary products include measures of the mean magnetic activity associated with the tracked cubes, rotation averages of the power spectra at different Stonyhurst locations, and long-term averages of the input Dopplergrams. Active efforts are currently underway to improve many of these products. We review recent changes to the analysis procedures and products, discuss known problems, and describe modifications and updates in progress, under development, and/or contemplated for the near future.
