Caption: Figure 5.
Background-subtracted pulsed fraction of PSR A (top panels) and orbital modulation of the total count rate from the system (bottom panels), in the 0.15–3.0 keV energy interval, obtained by folding ∼67 orbital periods (2006+2011 EPIC-pn data) and binning at ∼40 minutes (left) and ∼20 minutes (right). The vertical dotted–dashed line represents the superior conjunction of PSR A.
