The Fourth BATSE Gamma Ray Burst Catalog contains a set of tables that characterize the gamma-ray bursts that have been detected with BATSE. This catalog covers bursts detected up to and including 29 August 1996. The following tables comprise the 4B Catalog:
Table Name | Description |
---|---|
Basic | The BATSE trigger number, burst name, time of trigger, derived source direction, angle from geocenter to burst direction, information about burst overwrites for each burst. This table contains 1637 triggers. |
Flux and Fluence | Includes BATSE trigger number, peak flux on the 64 ms, 256 ms, and 1.024 s trigger timescales, and fluences in four energy channels for each burst. This table contains 1292 triggers. |
CMAX/CMIN | The table gives the BATSE trigger number, cmax/cmin and cmin values for the 64 ms, 256 ms and 1.024 s trigger timescales for each burst. This table contains 912 triggers. |
Duration | The table gives the BATSE trigger number, and the durations required for integration of 50% and 90% of the burst fluence for each burst. This table contains 1234 triggers. |
Comments | Includes BATSE trigger number and free form comments for each burst. |
Exposure | The sky exposure as a function of declination is given for the 4B Catalog and several subsets. |
Trigger Efficiency | Describes the fraction of time a burst will be triggered on each of the trigger timescales as a function of GRB intensity. |
Trigger Criteria | Trigger threshold and energy range vs. time. |
