The BAT1 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.
