Notes. Details of the sample are provided in the columns as (1) burst name, (2) Galactic H i column density; (3) time of SED, time since GRB trigger; (4) Galactic E(B − V) from the Schlegel et al. (1998) extinction maps corrected for 14% overestimation; (5) redshift; and (6) magnitude of the afterglow from the acquisition image.
