ThERESA: Three-dimensional Exoplanet Retrieval from Eclipse Spectroscopy of Atmopsheres

ThERESA is a Python package for three-dimensional exoplanet retrieval from spectroscopic eclipse observations. It uses principle component analysis to fit a two-dimensional thermal map to light curves at each wavelength, or filter, then combines these maps into a three-dimensional atmosphere, computes emission across the planet using radiative transfer, and integrates over the planet to calculate light curves for comparison with observations.
