* T0 refers to the BAT trigger time
* All measurements use a source radius of 9 pixels (21 arcseconds), 
a background measurement from an annulus around the source region, and 
the Bayesian method of Kraft, Burrows, and Nousek (1991, ApJ, 374, 344) to obtain
the 1-sigma confidence intervals (for detections) or 3-sigma upper limits (for non-detections).
