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=12347=NGC4552,   delta=0.149 [deg].  
COMMENTS:        This matches a source in the ground catalog: NGC4552,   delta=0.149 [deg].  
COMMENTS:        Galaxy IC3540 (of total mag=15.00 and dia=0.40 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.
