Fig. 6.
Spectrum of the PN during the quiescent phase (top panel) and ratio data/model. The spectrum was accumulated from events collected during the quiescent phases after the flare and in the third XMM-Newton observation. The model is an absorbed APEC thermal component. A sharp excess of emission is visible at ∼6.4 keV and due to the fluorescent emission present even during quiescence.
