Notes. We note that Nint and NGRB are the total number of intervals and the number of GRBs, respectively, while , , and are the mean values and standard deviations of the distributions of the best-fit parameters of individual GRBs reported in Table 1. The luminosity is either isotropic-equivalent (iso) or collimation-corrected (coll).
