Notes. We refer to Sect. 3 for the value determinations, except for the dust optical depth, τd, which is converted from AV by considering a dust albedo of A = 0.5 (see Verhamme et al. 2006; Gronke et al. 2015). The asterisk stands for value determined from the FWHM of the [OIII]λ5007 line. “OA” is for the parameters related to optical afterglow observations and “HG” for the host galaxy parameters.
References. The AV values are reported in (1) Jakobsson et al. (2003), (2) de Ugarte Postigo et al. (2005), and (3) Troja et al. (2007); see Sect. 3 for more details.
