The Fourth BATSE Gamma-Ray Burst Catalog (Revised)

摘要

The Burst and Transient Source Experiment (BATSE) on the Compton Gamma RayObservatory (CGRO) has triggered on 1637 cosmic gamma-ray bursts between 1991April 19 and 1996 August 29. These events constitute the Fourth BATSE burstcatalog. The current version (4Br) has been revised from the version firstcirculated on CD-ROM in September 1997 (4B) to include improved locations for asubset of bursts that have been reprocssed using additional data. A significantdifference from previous BATSE catalogs is the inclusion of bursts from periodswhen the trigger energy range differed from the nominal 50-300 keV. We presenttables of the burst occurrence times, locations, peak fluxes, fluences, anddurations. In general, results from previous BATSE catalogs are confirmed herewith greater statistical significance.
