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=10568=4U_1901+03,   delta=0.067 [deg].  
COMMENTS:        This matches a source in the ground catalog: 4U_1901+03,   delta=0.067 [deg].  
COMMENTS:        There is a bright star (mag=6.73) 6.90 arcmin from this position.  
COMMENTS:        This is not a GRB.  
COMMENTS:        This is an interesting source.  
COMMENTS:           
COMMENTS:        The IMAGE_SIGNIF is VERY LOW, this is very likely not real.  
COMMENTS:        This trigger occurred at longitude,latitude = 260.96,6.18 [deg].
