Left: MJD 56816 (“Peak 1”) flare. Top panel: exposure rate as a function of time. Middle panel: measured (probability-weighted, blue) and modeled (red) photon counts. Bottom panel: light-curves. Blue points: 3 hr binning. Blue curve: function fitted to 3 hr points. Red curve: function fitted using the unbinned method. The green dashed line corresponds to the constant component and the blue one to the flare component F(t) given in Equation (5). Right: same for the MJD 56827 (“Peak 4”) flare.
