Here is an overview of the cumulative spectrum (about 260 ks) for combined MEG and HEG fluxes, for a bin size of 0.02 Å. Some significant lines are marked. The statistical counting uncertainty is shown in gray. The lower panel shows the residuals against the emission measure model. The integrated flux (1–40 Å) at Earth is 3.3 × 10 ⁻¹² erg cm ^-2 s ⁻¹ (1.3 × 10 ⁻³ phot cm ^-2 s ⁻¹).
