XSGRB afterglow sample

This release is the XS-GRB sample of Gamma-Ray Burst (GRB) afterglows. It consists of spectra of 103 individual afterglows observed within 48 hours of the GRB trigger and a few late-time host observations, included for completeness. Redshifts have been measured for 97 per cent of these, covering a redshift range from 0.059 to 7.84. These X-shooter spectra have been taken during a period of eight years corresponding to the ESO observing periods P84 through P98. This dataset provides a unique resource to study the ISM across cosmic time, from the local progenitor surroundings to the intervening universe. The data and scope are described in Selsing et al. (2019, A&A, 623, 92S).
