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:        There is a bright star (mag=5.97) 8.42 arcmin from this position.  
COMMENTS:        This is a GRB.  
COMMENTS:        Since the foreground interval count rate is less than the bkg interval (SAA exit), this is a questionable detection.  
COMMENTS:        This trigger occurred at longitude,latitude = 104.17,1.23 [deg].
