Notes. Burst durations are given in the observer frame and were taken from The isotropic-equivalent energies (in units of erg) were derived from the observed high-energy properties (Briggs & Younes 2011; Golenetskii et al. 2013), and using the statistically inferred high-energy properties of GRBs (Butler et al. 2007). Lγ, iso is the time-averaged luminosity (erg s−1) of the burst, here defined as Eiso/T90. References for the redshifts are given in Appendix A.
