Welcome to the documentation for jwst. This package contains the Python software suite for the James Webb Space Telescope (JWST) calibration pipeline, which processes data from all JWST instruments by applying various corrections to produce science-ready, calibrated output products including fully calibrated individual exposures as well as high-level data products (mosaics, extracted spectra, etc.). The tools in this package allow users to run and configure the pipeline to custom process their JWST data. Additionally, the jwst package contains the interface to JWST datamodels, the recommended method of reading and writing JWST data files in Python.

If you have questions or concerns regarding the software, please contact the JWST Help desk at JWST Help Desk.
