ExoIris is a Python package for exoplanet transmission spectroscopy that models the full 2D spectroscopic transit time series directly, replacing the traditional two-step workflow. It jointly fits spectrophotometric datasets from different instruments and epochs in a single self-consistent analysis — and does so fast, completing a typical JWST transmission spectrum in tens of minutes on a standard desktop.
See the documentation & Tutorials for details, examples, and API reference.
