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.
