COMMENTS:        SWIFT-BAT GRB Coordinates.  
COMMENTS:        This is an image trigger.  (The RATE_SIGNIF & BKG_{INTEN, TIME, DUR} are undefined.)  
COMMENTS:        A point_source was found.  
COMMENTS:        This matches a source in the on-board catalog: Num=15709=(null) (probably an AT_Slot).  
COMMENTS:        This matches a source in the ground catalog: IGR_J17364-2711,   delta=0.180 [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 = 175.29,1.35 [deg].
