Same as Fig. 3, but for Obs1. Individual burst profiles are shown in black, with different line styles. Five bursts are required for the 0.2 − 0.4 keV and 0.4 − 0.6 keV bins, while four are needed for 0.6 − 0.8 keV and three in the remaining energy bins (see Table A.1). Lower panels: data/model ratios. Vertical lines indicate t_start of each burst at all energies, with the line style matching the one used for the burst profiles in the upper panels with the light curves. Shaded intervals show 1σ uncertainties.
