Properties of the prompt emission for different classes of GRBs in the plane [85]. Data from [85–87] are shown in grey along with their best fit to a single power law (index of ) and the 2 uncertainty in their fit. Notable events that do not appear to follow the Amati relation include GRBs (980425 and 031203), INT-GRBs (150818A), and high-luminosity GRB 140606B. Both ULGRBs are consistent with the Amati relation, so are GRBs 030329 and 130427A, while GRB 120422A and GRB 100316D are marginally consistent.
