The BATSE Trigger data (each trigger is specified by a unique trigger number) are a set of triggered events that are classified as either a (solar) flare, (gamma-ray) burst, soft gamma-ray repeater (sgr), terrestrial gamma flash (tgf), or tagged with the name of a known source. Not all triggers pass the acceptance tests, so not all trigger numbers are present. For each trigger, there is an associated set of FITS data files that represent the raw data sources and some higher level data products. Spectral (SD) data are prefixed with an 's' (e.g. 'sher'). Not all data types are available for all triggers due to instrument mode differences. Available data taken prior to the trigger may contain the beginning of the triggering event before it satisfied the triggering criteria. Background-type files can be used to remove background signal levels from the triggered period. The BFITS data files - containing burst and background spectral data as a function of time - and the detector response matrices (DRM) - modeling the instrument response to account for scattering and other effects - are extremely useful for gamma-ray burst analysis. Also, the BFITS and DRM files can be converted to PHA-II and RMF format for analysis with XSPEC using available FTOOLS. Please refer to the Data_Products section for more details on the various file types. A current description of the BATSE data holdings including the TRIGGER files is also available in the 1998 Legacy article, online at: <pre> <a href="https://heasarc.gsfc.nasa.gov/docs/journal/cgro7.html">https://heasarc.gsfc.nasa.gov/docs/journal/cgro7.html</a>; </pre> General information about BATSE is available at the Compton Observatory Science Support Center (COSSC) web site at: <pre> <a href="https://heasarc.gsfc.nasa.gov/docs/cgro/batse/">https://heasarc.gsfc.nasa.gov/docs/cgro/batse/</a>; </pre> This database table was created through a cooperative effort of the HEASARC and the Compton Observatory Science Support Center (COSSC). The table data were last updated in November, 2003. The HEASARC added Galactic coordinates in August, 2005. The "_trigger" field was renamed to "trigger_id" in September, 2020. This is a service provided by NASA HEASARC .
