The [jwst](/auth0/node-jws) package processes uncalibrated data from the James Webb Space Telescope (JWST), an orbiting infrared observatory at Earth-Sun L2. It performs a series of calibration steps, converting raw data into standard data products suitable for scientific analysis. This includes corrections for instrumental effects and atmospheric contributions. The pipeline leverages calibrated reference data from the Calibration Reference Data System (CRDS).
The pipeline ensures data consistency by utilizing CRDS for reference files, offering a standardized calibration process. It's designed with modularity, allowing for flexible calibration workflows. The package supports various JWST instruments, and it has a well-defined setup process for integration with the CRDS. The implementation prioritizes reproducibility and offers options for building from source or using pre-built environments.
