Notes. We show both the highest-likelihood model parameters from a maximum-likelihood (ML) estimation and the median values along with their corresponding 1σ confidence intervals from the MCMC marginalised posterior distributions presented in Fig. 8. The beaming-corrected prompt γ-ray and kinetic energies are given in the lower panel of the table, where we have placed a lower limit on the opening angle of the jet based on a limit of tjet ≳ 118 days.
