Beginning of ReadMe : J/ApJS/175/179 The BAT1 gamma-ray burst catalog (Sakamoto+, 2008) ================================================================================ The first Swift BAT gamma-ray burst catalog.

This catalog (hereafter the BAT1 catalog) contains burst trigger time, location, 90% error radius, duration, fluence, peak flux, and time-averaged spectral parameters for each of 237 GRBs, as measured by the BAT. The BAT-determined position reported here is within 1.75' of the Swift X-Ray Telescope (XRT)-determined position for 90% of these GRBs. The BAT T_90_ and T_50_ durations peak at 80 and 20s, respectively. From the fluence-fluence correlation, we conclude that about 60% of the observed peak energies, E^obs^_peak_, of BAT GRBs could be less than 100keV. We confirm that GRB fluence to hardness and GRB peak flux to hardness are correlated for BAT bursts in analogous ways to previous missions' results. The correlation between the photon index in a simple power-law model and E^obs^_peak_ is also confirmed. We also report the current status for the on-orbit BAT calibrations based on observations of the Crab Nebula. Description: The BAT is a highly sensitive, large field of view (FOV) (1.4sr for >50% coded FOV and 2.2sr for >10% coded FOV), coded-aperture telescope that detects and localizes GRBs in real time. The fast and accurate BAT GRB positions with 1'-3' error radii are the key to autonomously slewing the spacecraft to point the XRT and the the Swift UV/Optical Telescope (UVOT).
