COMMENTS:        SWIFT-BAT GRB Coordinates.  
COMMENTS:        This Notice was delayed by more than 60 sec past the end of the trigger integration interval;  
COMMENTS:        probably due to it occurring during a Malindi downlink session.  
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=15753=(null) (probably an AT_Slot).  
COMMENTS:        This matches a source in the ground catalog: IGRJ18245-2452,   delta=0.023 [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 = 212.45,-14.81 [deg].  
COMMENTS:           
COMMENTS:        NOTE: This BAT event is spatially(0.00<0.1deg) coincident with the SWIFT_BAT event (trignum=552369).
