About JDox

JWST User Documentation, informally known as "JDox," is intended as an agile, user-friendly source of information inspired by Wikipedia articles. Our goal is to provide short, focused, well-linked articles covering details about the observatory and instruments, descriptions of tools used for proposing, advice on observing strategies, roadmaps that guide users through the proposal preparation process, as well as information about calibration and analysis of JWST data.

In addition to the User Documentation designed for proposers, JDox also includes a subsidiary section called Proposal Parameters articles that contain technical documentation for each "field" (parameter) in the Astronomer's Proposal Tool (APT).   These articles are not designed as a primary reference and not displayed on the left-had navigation sidebar of the User Documentation. However, some links throughout JDox may point you to a Proposal Parameters article for specific information.  If the article you are viewing is in the Proposal Parameters area, the left-hand sidebar will look different and the background color will change.  To return to the User Documentation, use the JDox HOME button at upper left.
