ECL_COORDS:      346.37,-25.50 [deg] ecliptic lon,lat of the burst (or transient)
COMMENTS:        SWIFT Figure-of-Merit decision.  
COMMENTS:        This Notice is generated as a result of an uploaded TOO on an old GRB -- this is not a newly detected burst.  
COMMENTS:        As a result of this TOO, the TRIG_INDEX, and RATE/IMAGE_SIGNIF fields are not valid!  
COMMENTS:        And sometimes the GRB_DATE/TIME fields are not valid!  
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 TOO or ground catalogs.
