About This Article

A new JDox page provides the latest estimated uncertainties for JWST calibrated quantities, such as photometry, astrometry, and wavelength calibration. To facilitate navigation, the page is organized by instrument and mode. Each section is time-stamped so the latest updates are easily identifiable. Values will be updated as the understanding of the instruments’ calibration evolves. 

Please let us know if you have questions or comments via the JWST Help Desk, using the instrument-relevant card.
