Ring Diagrams
This section describes the data analysis pipelines that are used to produce spatially-resolved data describing the fluid motions and thermal structure in the sub-surface regions of the solar convection zone using the techniques of ring-diagram analysis applied to the HMI Dopplergram data series. Two pipelines are involved, one producing synoptic views of the flows and structure on regular spatial grids, and the other producing detailed flow and structure anomalies associated with specific target regions. We will refer to these as the synoptic and target pipelines, respectively. Both have common requirements for most of the analysis modules and data structures, so it is appropriate to consider them together.
