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=10763=(null) (probably an AT_Slot).  
COMMENTS:        This matches a source in the ground catalog: V_404_Cyg,   delta=0.018 [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 = 229.00,-11.52 [deg].  
COMMENTS:           
COMMENTS:        NOTE: This BAT event is spatially(0.00<0.1deg) and temporally(3.0<100sec) coincident with the SWIFT_BAT event (trignum=668879).
