COMMENTS:        SWIFT Figure-of-Merit decision.  
COMMENTS:        This was of sufficient merit to become the new Automated Target;  
COMMENTS:        but if the Current PPT has a greater merit, then we will not request a slew.  
COMMENTS:        This matches a source in the ground catalog: NGC3184,   delta=0.098 [deg].  
COMMENTS:        The position is inside the galaxy NGC3184 (of total mag=9.80 and dia=6.90 arcmin).  
COMMENTS:        There is a 0.03% probability that this would happen by chance coincidence.  
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 = 221.12,-15.91 [deg].
