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=23771=(null) (probably an AT_Slot).  
COMMENTS:        This does not match any source in the ground catalog.  
COMMENTS:        This is not a GRB.  
COMMENTS:        This is an interesting source.  
COMMENTS:        Since the IMAGE_SIGNIF is less than 7 sigma, this is a questionable detection.  
COMMENTS:        This trigger occurred at longitude,latitude = 163.00,-4.40 [deg].  
COMMENTS:           
COMMENTS:        NOTE:  This location is less than 10arcmin from the boresight -- Swift was already looking at this source.  
COMMENTS:           
COMMENTS:        NOTE: This BAT event is spatially(0.00<0.1deg) coincident with the SWIFT_BAT event (trignum=813772).
