CaSSI provides search and access to restricted JWST mission product categories, including pre-launch test data, and raw science and engineering telemetry files from the spacecraft.
In this chapter...
Product Data Group
The products available for JWST are grouped by category, as summarized in the subsections below; each may require a separate authorization for data retrieval.
Select the desired JWST data group from the pull-down menu in the CaSSI Web interface, as shown at right.
SID
The Science Instrument ground-test Data archive (SID), selected via the Instrument Integration and Test Data group, includes all products produced during pre-launch ground testing of the JWST science instruments flight hardware, including data obtained in the thermal-vacuum environment. See the SID article (not yet available) for details of the interface to these products. Note that product search is restricted to authorized users.
Supplemental and Engineering Telemetry
Products from JWST include dumps of the science data recorder and the full engineering telemetry stream from the spacecraft. Ordinarily these products are used by the science data pipeline to produce science and engineering products, and by expert staff to troubleshoot issues. See the JWST Supplemental Products article to learn how to search for and retrieve these products. Note that product download is restricted to authorized users.
