Distribution of the background-subtracted J12270 count rate obtained from 20 s binned lightcurves from the 2009 January and 2011 January XMM-Newton EPIC data. We define the region between 0 cts s⁻¹ and 2 cts s⁻¹ as the low-soft mode, while the region between 4.6 cts s⁻¹ and 9 cts s⁻¹ is the high mode. Higher than 12 count s⁻¹ we define flare mode. In the zoomed plot we can see that the double Gaussian fit does not interpolate data during the flares.
