The GUSBAD catalog is based on BATSE DISCLA data at a time resolution of 1024 msec for the full Compton Gamma Ray Observatory (CGRO) mission from April 19, 1991 till May 26, 2000 (TJD 8365-11690). The catalog lists 2207 gamma-ray bursts (GRB).
Selection of GRBs for the GUSBAD catalog requires an excess of 5 sigma over background in two of the BATSE detectors over the energy range 50-300 keV. The search covers the entire mission except when CGRO was in particular geographic regions or during one of 199,964 time windows when DISCLA data were missing or contaminated. The classification as GRB or non-GRB of the 6236 events that were produced by the software trigger was aided by correlating the times and positions of the events against the Current Batse Burst Catalog. There are 589 GRBs in the GUSBAD catalog that are not included in the Current Batse Burst Catalog.
The GUSBAD catalog is uniform in the sense that the detection criterion is the same throughout and that the properties given in the catalog are available for every burst. The detection and the derivation of the properties listed in the catalog were carried out automatically, except for some rare instances. This makes the catalog especially suitable for statistical work and simulations, such as used in the evaluation of V/Vmax.
The procedure used to detect and classify the bursts has been described in ApJ 616, 1072, 2004. Part of the BATSE DISCLA data were obtained from the HEASARC archive, provided by NASA's Goddard Space Flight Center.
The GUSBAD catalog consists of a single table. The description of the catalog provides information about each of the properties and illustrates the format using the first entry GUSBAD 910419.041 as an example.
