cds-question@unistra.frgamma-ray-astronomyWe present the second Swift Burst Alert Telescope (BAT) catalog of gamma-ray bursts (GRBs), which contains 476 bursts detected by the BAT between 2004 December 19 and 2009 December 21. This catalog (hereafter the BAT2 catalog) presents burst trigger time, location, 90% error radius, duration, fluence, peak flux, time-averaged spectral parameters, and time-resolved spectral parameters measured by the BAT. In the correlation study of various observed parameters extracted from the BAT prompt emission data, we distinguish among long-duration GRBs (L-GRBs), short-duration GRBs (S-GRBs), and short-duration GRBs with extended emission (S-GRBs with E.E.) to investigate differences in the prompt emission properties. The fraction of L-GRBs, S-GRBs, and S-GRBs with E.E. in the catalog are 89%, 8%, and 2%, respectively. We compare the BAT prompt emission properties with the BATSE, BeppoSAX, and HETE-2 GRB samples. We also correlate the observed prompt emission properties with the redshifts for the GRBs with known redshift. The BAT T90 and T50 durations peak at 70s and 30s, respectively.2011ApJS..195....2Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/195/2CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIX/20 : The Fourth BATSE Burst Revised Catalog (Paciesas+ 1999)J/MNRAS/407/2075 : Gamma-ray bursts spectral peak estimator (Shahmoradi+, 2010)J/ApJ/693/1484 : Early optical afterglow catalog (Cenko+, 2009)J/PAZh/35/10 : Gamma-ray bursts with known redshifts (Badjin+, 2009)J/ApJS/180/192 : BeppoSAX/GRBM {gamma}-ray Burst Catalog (Frontera+, 2009)J/ApJS/175/179 : The BAT1 gamma-ray burst catalog (Sakamoto+, 2008)J/ApJS/166/298 : Spectral catalog of bright BATSE gamma-ray bursts (Kaneko+,J/A+A/385/377 : 319 gamma-ray bursts BATSE triggers (Quilligan+, 2002)J/ApJ/563/80 : 3906 gamma-ray bursts BATSE triggers (Stern+, 2001)J/ApJS/134/385 : Supplement to the BATSE gamma-ray burst catalogs (Kommers+,J/ApJS/126/19 : BATSE gamma-ray burst spectral catalog.
