The Calibration and Supplemental Search Interface (CaSSI) provides access to the full set of uncommonly accessed and restricted JWST and Roman mission product categories. The products include pre-launch test data, telemetry and, and for Roman, calibration reference products. CaSSI also offers an API for search and data retrieval. On this page...

| Warning |
|---|
Some of the CaSSI functionality has not yet been implemented, and not all intended data products are available. This guide will display pages that correspond to deployed interfaces, but may refer to features that are not yet available. |
Data Category Selection
The product search interfaces are segregated by mission and data group. Select the mission in the Web interface with the pull-down menu, as shown at right for the Roman mission.
Limitations
Be aware that the CaSSI web interfaces will return no more than 5000 results. If the reported number of matches in the results table rows is exactly 5000 it likely means that not all matching archived products are displayed. Repeat the search with additional more restrictive search criteria to keep the results to within the limit. An alternative is to retrieve a curl script via the Show API Query button, remove the limit from the script, and execute the search from the command line.
| Note |
|---|
| Some data groups, such as supplemental JWST data, include millions of files. If you execute an API search with increased or missing limits, the search may return very large numbers of results. Such searches may take many minutes to execute, or may time out on the server. It is best to start with highly restrictive search criteria, or to first perform a count of the number of results, before performing an extensive or unconstrained query. |
Authorization
All except the calibration product categories available in CaSSI require explicit per-user authorization. Please login to CaSSI to retrieve data. If you need, but do not have, authorization , contact the MAST Archive Support to request it, mention the mission for which you need authorization, and describe the functional reason for the request.
User Support
