Notes. Uncertainties on the fluxes include data and line-fitting uncertainties, but not calibration uncertainties, which are on the order of 5% for the Spitzer lines and 15% for the Herschel lines. Critical density and ionization potential values are taken from Cormier et al. (2012). Critical densities are noted [e] for collisions with electrons and [H] for collisions with hydrogen atoms.
