COMMENTS:        SWIFT Figure-of-Merit decision.  
COMMENTS:        This was NOT of sufficient merit to become the new Automated Target.  
COMMENTS:        FOM will NOT request the s/c to slew.  
COMMENTS:        This matches a source in the ground catalog: SwJ1922.7-1716,   delta=0.166 [deg].  
COMMENTS:           
COMMENTS:        The next comments were copied from the BAT_POS Notice:  
COMMENTS:        This is an image trigger.  (The RATE_SIGNIF is undefined.)  
COMMENTS:        A point_source was found.  
COMMENTS:        This matches a source in the on-board catalog.  
COMMENTS:        This is not a GRB.  
COMMENTS:        This is an interesting source.  
COMMENTS:           
COMMENTS:        The IMAGE_SIGNIF is VERY LOW, this is very likely not real.  
COMMENTS:        This trigger occurred at longitude,latitude = 120.28,10.34 [deg].
