COMMENTS:        This is an image trigger.  (The RATE_SIGNIF & BKG_{INTEN, TIME, DUR} are undefined.)  
COMMENTS:        A point_source was found.  
COMMENTS:        This is a low-flux event whose position matches one of the nearby galaxy sources in the on-board catalog!  
COMMENTS:        This matches a source in the on-board catalog: Num=12135=NGC3184,   delta=0.098 [deg].  
COMMENTS:        This matches a source in the ground catalog: NGC3184,   delta=0.098 [deg].  
COMMENTS:        The position is inside the galaxy NGC3184 (of total mag=9.80 and dia=6.90 arcmin).  
COMMENTS:        There is a 0.03% probability that this would happen by chance coincidence.  
COMMENTS:        This is a GRB in nearby galaxy or it is noise.
