Fluence distributions derived from the power-law model SPL (top) and the blackbody model SBB (bottom) for all bursts. Different histograms represent magnetar groups as defined in Figure 2 and indicated in the legend. The black lines show the best-fit power-law functions for the full burst sample, with indices of −0.52 ± 0.03 for the power-law model and −0.53 ± 0.04 for the blackbody model. The gray lines show the best-fit power-law functions for the sample excluding SGR 1935+2154, with indices of −1.00 ± 0.06 and −0.94 ± 0.06 for the two spectral models.
