(a) The E_iso and E_γ,beam of the prompt emission of the 105 hyper-energetic GRBs are shown in green squares and red circles, respectively. The horizontal gray dashed line marks 10⁵² erg. (b) The distributions of θ_j and E_γ,beam of the 105 hyper-energetic GRBs are shown in the left and right panels of the plot, respectively. The log-normal fits to the respective distributions are shown in dashed green lines. The means of θ_j and E_γ,beam distributions are 2.°1 ± 0.°9 and (1.9 ± 4.2) × 10⁵¹ erg, respectively.
