Analysis
This paper introduces ExoAtom, a database extension of ExoMol, providing atomic line lists in a standardized format for astrophysical, planetary, and laboratory applications. The database integrates data from NIST and Kurucz, offering a comprehensive resource for researchers. The use of a consistent file structure (.all, .def, .states, .trans, .pf) and the availability of post-processing tools like PyExoCross enhance the usability and accessibility of the data. The future expansion to include additional ionization stages suggests a commitment to comprehensive data coverage.
