Time-resolved spectroscopy using the f_a model (red dot) and the disk reflection model (blue square) for bursts #1–8. For each panel, from top to bottom, we exhibit the burst bolometric flux, F_burst; the blackbody temperature, kT_bb, and the blackbody radii, R_bb, which were calculated using a distance of 7.54 kpc; the enhanced persistent emission flux and disk reflection flux, F_fa and F_refl, respectively; and the goodness of fit per degree of freedom, red χ². The gray dashed-dotted lines mean the persistent emission level, and the black dashed lines label the touchdown moment of the f_a model. The red χ² of the blackbody model are plotted as a gray dashed line for comparison.
