Table 9: Flux of the broad emission lines, from the simultaneous LETGS, MEG and HEG fit. The wavelength was frozen to the rest wavelength of the line, while the FWHM was frozen to 8000 km s-1. The lines for which upper limits are detected were not used in the further analysis of the data.

a This coincides with the instrumental C-edge, therefore its detection is less certain due to possible calibration uncertainties.
b The resonance intercombination and forbidden lines significantly overlap, so separate measurements are difficult.
