Comparison of the literature standard abundance tables of Fe, O, and S with the values of this work derived from FUV and X-ray observations presented in Table 5. The log(O/Ne) ratio is the sum of the predicted O I abundance that we obtain from a simultaneous X-ray and FUV fit and the solid-phase oxygen. For the log(Fe/Ne) ratio, we used the combined contribution of solid iron and atomic Fe II. Please note that the log(S/Ne) ratio comes from the S II value only resulting from the FUV fit. The Ne abundance is determined through the fit of the Ne K-edge in the X-ray spectrum from Psaradaki et al. (2023); in particular, it represents the summed abundance of Ne I, Ne II, and Ne III.
