COMMENTS:        SWIFT-BAT GRB Coordinates.  
COMMENTS:        This is a rate trigger.  
COMMENTS:        A point_source was found.  
COMMENTS:        This does not match any source in the on-board catalog.  
COMMENTS:        This does not match any source in the ground catalog.  
COMMENTS:        This is not a GRB.  
COMMENTS:        Since the IMAGE_SIGNIF is less than 7 sigma, this is a questionable detection.  
COMMENTS:        This is a RETRACTION of a previous notice that identified this as a GRB -- it is NOT a GRB.  
COMMENTS:        This Notice was ground-reprocessed from flight-data.  
COMMENTS:          
COMMENTS:        This trigger is NOT due a real GRB, nor any astrophysical source.  
COMMENTS:        This trigger was caused by a cosmic ray shower event in the intrument.  
COMMENTS:        All the vents occurred in a single 100-microsec time bin.
