Processed data repository class

The processed data repository structure contains products created by the ISDC processing pipelines, along with their auxiliary and calibration data. This structure is used both for temporary storage of data products by the system pipelines as they process data and for long term storage in the archive. Each processed data repository structure has a high level directory structure as shown in Figure 13.

• idx contains ISDC index files used for fast searching of data for selected data products,
• obs contains results of Science Analysis,
• scw contains the results of processing from the science window pipelines on a per-science window basis.
