Time-resolved spectroscopy using the f_a model (red dot) and the disk reflection model (blue square) for bursts #2 (left column), #8 (middle column), and #15 (right column). Shown in each column, from top to bottom, are the burst bolometric flux, F_burst; the blackbody temperature, kT_bb, the blackbody radii, R_bb, which were calculated using a distance of 8.4 kpc; the enhanced persistent emission flux and disk reflection flux, and F_red, respectively; and the goodness of fit per degree of freedom, . The red dash-dotted lines represent the persistent emission level. The of the blackbody model are plotted as gray dashed lines for comparison.
