COMMENTS:        A point_source was found.  
COMMENTS:        This matches a source in the on-board catalog: Num=25400=(null) (probably an AT_Slot).  
COMMENTS:        This matches a source in the ground catalog: Crab,   delta=0.264 [deg].  
COMMENTS:        This is not a GRB.  
COMMENTS:        This is an interesting source.
