The data products and catalogs to be archived in addition to the raw data are detailed in Chapter 3. Before launch, however, it is difficult to anticipate all the Astro-D data products that we shall want to catalog and archive. For example, it may prove impossible, with data of Astro-D quality, to fit spectra automatically. In view of this, the pipeline and catalog system is intended to be sufficiently fast and flexible that additions and modifications to the Astro-D database be straightforward to implement.
