COMMENTS:        SWIFT-BAT GRB Coordinates.  
COMMENTS:        This is a rate trigger.  
COMMENTS:        A point_source was found.  
COMMENTS:        This matches a source in the on-board catalog: Num=10597=Kes 73,   delta=0.017 [deg].  
COMMENTS:        This matches a source in the ground catalog: Kes 73,   delta=0.017 [deg].  
COMMENTS:        This is not a GRB.  
COMMENTS:        Since the IMAGE_SIGNIF is less than 7 sigma, this is a questionable detection.  
COMMENTS:        This trigger occurred at longitude,latitude = 125.46,19.52 [deg].  
COMMENTS:        This AT will self-cancel at the end of the first orbit (ie I_signif<7.0 && Trig_dur<65msec).
