The official—and most up-to-date—JWST user documentation are available in the webpage articles on this website.

Downloadable PDF collections of the documentation are provided below as a courtesy, made available and updated when feasible.

Updated August 15, 2023

The PDF documents listed below were created on August 15, 2023. They include in-flight performance information from observatory commissioning data and some Cycle 1 calibration data.

From August 15 to October 25, 2023, all content related to Cycle 3 proposal preparation will be frozen. However, content regarding data calibration and analysis will continue to be updated as needed. Please see Breaking News for additional information.
