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.  
COMMENTS:        This matches a source in the ground catalog: PKS 0528+134,   delta=0.181 [deg].  
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 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 is not a GRB.    
COMMENTS:        We believe this to be a cosmic ray shower event.  
COMMENTS:        All the counts are in the high energy band and the trigger duration is short.  
COMMENTS:        And the image significance is very low.  
COMMENTS:        The location with the pulsar is believed to be a coincidence.
