Spectrum of ObsID 11044, displayed as the ratio between data and absorbed power-law continuum model. The most prominent absorption and emission lines have been fitted with Voigt profiles. The Lyα lines of H-like Si, Mg, and Ne show clear P Cygni profiles. The absorption line at 6.70 Å, however, cannot be related to the emission line at 6.74 Å, if the latter is due to the (dipole-) forbidden transition of Si xiii.
