Figure 12: (a) The relation. The open squares mark the BATSE data. BeppoSAX events, which are converted into the energy range of , are shown as filled squares and the cross points. The solid line indicates the best-fit line. (Figure after Yonetoku et al. [116]; see Figure therein. @ AAS. Reproduced with permission.) (b) versus for 276 time-resolved spectra within the decay pulses for the sample. The solid line stands for the best fit to the data. (Figure after Lu and Liang [230]; see Figure therein.
