GAL_COORDS:       84.61, 53.94 [deg] galactic lon,lat of the burst (or transient)

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:        FOM will request the s/c to slew.  
COMMENTS:        The S/C has yet to make its decision about safe to slew or not.  
COMMENTS:        This does not match any source in the ground catalog.  
COMMENTS:           
COMMENTS:        The next comments were copied from the BAT_POS Notice:  
COMMENTS:        This is a rate trigger.  
COMMENTS:        A point_source was found.  
COMMENTS:        This does not match any source in the on-board catalog.  
COMMENTS:        This is a GRB.  
COMMENTS:        Since the IMAGE_SIGNIF is less than 7 sigma, this is a questionable detection.  
COMMENTS:        This trigger occurred at longitude,latitude = 159.91,-16.99 [deg].
