The STScI/JWST pipeline automatically processes data for all available observing modes. Details of the pipeline architecture and algorithms can be found here. Each branch of the pipeline uses a set of instrument-specific reference files that ensure the pipeline meets its accuracy requirements.
The JWST pipeline provides science-ready calibrated data for all offered instruments/observing modes. The pipeline relies on the use of a set of reference files to ensure the correct and accurate process of the data. The reference files are instrument-specific, and are periodically updated as the data process evolves and the understanding of the instruments improves. The following links provide information on the individual reference files used by the JWST instrument in the different pipeline stages.
