It includes the gamma-ray bursts from the BATSE 4B Catalog (triggers 105 through 5586, observed between April 19, 1991, and August 29, 1996) as well as a large number of triggered bursts since the publication of the BATSE 4B Catalog. All BATSE trigger data from the CGRO mission are available through this facility. As part of a final archiving effort, the BATSE instrument team is making minor refinements to certain data products. These revised products will be delivered to the HEASARC as soon as they are produced and tested. Certain burst catalog parameters, notably the position information, may be revised through improved analyses and instrumental calibration. The final catalog will be posted here as soon as it is completed. The data files used to construct this database table are obtained from the following pages on the BATSE GRB Team website: <pre> BATSE Current Gamma-Ray Burst Catalog: <a href="http://gammaray.msfc.nasa.gov/batse/grb/catalog/current/">http://gammaray.msfc.nasa.gov/batse/grb/catalog/current/</a> Some flux and fluence data and all the comments are from the BATSE 4B Catalog: <a href="http://gammaray.msfc.nasa.gov/batse/grb/catalog/4b/">http://gammaray.msfc.nasa.gov/batse/grb/catalog/4b/</a> </pre> <p> This database table was first created at the HEASARC in June 2001. The HEASARC version is automatically updated within one week of whenever the data files located at <a href="http://gammaray.msfc.nasa.gov/batse/grb/catalog/current/">http://gammaray.msfc.nasa.gov/batse/grb/catalog/current/</a> are changed.
