The GRB Afterglow table contains intensity and redshift measurements obtained with ground based telescopes or with space based observatories carried out after the detection of the GRBs. The catalog has been created using information from journal publications, IAU circulars, and GCN notices, and records afterglow measurements for bursts detected after May 1996. Each record within this catalog is dedicated to a specific measurement of an afterglow made with an observatory. Therefore for a given GRB, there are several entries reporting afterglow measurements from the different observatories. This catalog is linked to the main GRB catalog and it is updated when a new GRB and/or afterglow measurements are reported. This table was ingested by the HEASARC in June 2008 based on electronic versions obtained from the author(s), who compiled the catalog in 2005. This is a service provided by NASA HEASARC .
