Notes. Only the lines that are strong enough, span a large enough range of upper level energies (Eup), and have no significant velocity structure included. The notes include the reduced χ2 of the fit (
) and the identification number for the molecular model used in CASSIS, taken from the JPL database (https://spec.jpl.nasa.gov/).
