AMI AnalyseΒΆ

This step applies the Lacour-Greenbaum (LG) image plane modeling algorithm to a NIRISS Aperture Masking Interferometry (AMI) image. The routine computes a number of parameters, including a model fit (and residuals) to the image, fringe amplitudes and phases, and closure phases and amplitudes.

This link to the JWST pipeline provides detailed information on this step.
