The latest version of the JWST Science Calibration Pipeline (Build 10.2) overhauled level 3 calibration for NIRISS Aperture Masking Interferometry (AMI). Key changes include:

• Input Files: Default input is now 3D “calints” files. 2D “cal” images are supported but lack observable error calculations.
• Bad Pixel Correction: Automated Fourier-based correction applied during the AmiAnalyze step (see Figure 1 for an example).
• Output Format: Conforms to OIFITS v2 standard, with output files “ami-oi.fits” and “aminorm-oi.fits.”
• Additional Products: AmiAnalyze can generate “amimulti-oi.fits” (per-integration observables) and “amilg.fits” (cleaned data, models, residuals).
• No Averaging: AmiAverage step deprecated pending further analysis.
• Reference Files: Updated filter throughput and NRM reference files used.

This build will be used to process all new AMI datasets and to reprocess all existing archival data. For more details, visit the JWST Pipeline Documentation.  Users seeking more information on the NIRISS AMI Calibration update are encouraged to reach out to the JWST Help Desk using the NIRISS card.
