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=14051=M31_-1,-1,   delta=0.157 [deg].  
COMMENTS:        This matches a source in the ground catalog: M31_-1,-2,   delta=0.121 [deg].
