COMMENTS:        A point_source was found.  
COMMENTS:        This matches a source in the on-board catalog: Num=22487=(null) (probably an AT_Slot).  
COMMENTS:        This does not match any source in the ground catalog.  
COMMENTS:        This is not a GRB.  
COMMENTS:        This is an interesting source.
