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=15702=(null) (probably an AT_Slot).  
COMMENTS:        This matches a source in the ground catalog: XTE_J1814-338,   delta=0.173 [deg].  
COMMENTS:        This is not a GRB.  
COMMENTS:           
COMMENTS:        The IMAGE_SIGNIF is VERY LOW, this is very likely not real.  
COMMENTS:        This trigger occurred at longitude,latitude = 260.75,-19.18 [deg].
