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=12104=NGC5194,   delta=0.168 [deg].  
COMMENTS:        This matches a source in the ground catalog: NGC5195,   delta=0.112 [deg].  
COMMENTS:        Galaxy NGC5195 (of total mag=9.60 and dia=5.40 arcmin) is inside the position error circle.  
COMMENTS:        There is a 0.09% probability that an NGC galaxy would happen by chance coincidence.  
COMMENTS:        This is a GRB in nearby galaxy or it is noise.
