Isotropic-equivalent energetics for GBM GRBs with redshifts. This is a modified version of a figure in Abbott et al. (2017a). The total energetics (E_iso) is shown on the left and the 64 ms peak luminosity (L_iso) on the right. Both are given over the bolometric energy range from 1 keV to 10 MeV. GRBs best fit by a spectral model that constrains spectral curvature are shown as points. Power-law fits do not constrain spectral curvature and therefore overestimate the true value. GRBs best fit by a power law are shown as upper limits. The dashed black line is an approximate threshold for triggering GBM on-board.
