Notes. We report the energy, line width (σwidth), and equivalent width (EW) for each emission and absorption line; 𝒞−stat/ν is the fit statistic over the number of degrees of freedom; Δ𝒞 is the improvement in the fit statistic for each added component; Pℱ is the significance of each added component from F-test and Pℳ𝒞 is the significance based on Monte Carlo simulations (see section 5 and Appendix B for details).
