POSEIDON Input Files

This repository contains the input files required by the POSEIDON atmospheric retrieval code. The input files consist of molecular, atomic, and ionic cross sections, model grids of stellar spectra, and a chemical equilibrium grid. See the installation instructions (https://poseidon-retrievals.readthedocs.io/en/latest/content/installation.html) for the next steps after the download is complete. <strong>v1.1</strong> Added a chemical equilibrium grid computed with Fastchem 2. New, simplified, input file structure used by POSEIDON v1.1. One download, easier installation.
