Example of time-resolved spectroscopy of a burst for a burst from GS 1826-24 that was detected at MJD 51 811.750. The typical number of degrees of freedom in these spectral fits is 20. The panels from top to bottom show the time history of the bolometric flux of the best-fit model blackbody, its temperature, its normalization in terms of radius in km of emission sphere when located at 10 kpc distance, the fraction of the time that the detector is susceptible to photon detection (allowing for the detector dead time, see text), the best-fit f_a factor, and the reduced chi-squared of the fit.
