(2001) Non-Triggered Burst Supplement to the BATSE Gamma-Ray Burst (GRB) Catalog. It contains 873 "non-triggered" GRBs that were detected in a search of the BATSE Archival continuous data recorded between 1991 December 9 and 1997 December 17 for which the BATSE on-board burst trigger was not activated, for example because the burst was too faint to exceed the on-board detection threshold or it occurred while the on-board trigger was disabled for technical reasons. For each burst, the catalog gives an estimated source direction, duration, peak flux, and fluence. This catalog increases the number of GRBs detected using BATSE by 48% during the time period covered by the search. This database table was created at the HEASARC in September 2001 using the authors' file <a href="http://space.mit.edu/BATSE/ntgrb-ascii.html">http://space.mit.edu/BATSE/ntgrb-ascii.html</a> This is a service provided by NASA HEASARC . 2001ApJS..134..385K https://heasarc.gsfc.nasa.gov/W3Browse/all/kommersgrb.html Catalog Research served-by HEASARC TAP https://heasarc.gsfc.nasa.gov/xamin/vo/cone?showoffsets&table=kommersgrb& GET text/xml 180 99999 true 5.4 -87.3 5 https://heasarc.gsfc.nasa.gov/xamin/vo/tap https://heasarc.gsfc.nasa.gov/cgi-bin/W3Browse/getvotable.pl?name=kommersgrb GET text/xml https://heasarc.gsfc.nasa.gov/cgi-bin/W3Browse/w3query.pl?tablehead=name=heasarc_kommersgrb&Action=More+Options&Action=Parameter+Search&ConeAdd=1 GAMMA-RAY BURSTS 5 Gamma-ray public kommersgrb Kommers et al.
