Notes. GRBs in the sample. For each GRB, we report the basic information required in the analysis: redshift, Galactic extinction and equivalent neutral hydrogen column density in the burst’s line-of-sight, mid-time of the X-Shooter observation Tmid, and the time interval ΔTX (in ks) used for the construction of the X-ray part of the SED. Times are given relative to the start of the GRB γ-ray emission in the observer frame. GRB 130603B belongs to the short class, while other GRBs in the sample are of the long class.
