COMMENTS:        SWIFT SC Slew 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_SIGNIF fields are not valid!  
COMMENTS:        And sometimes the GRB_DATE/TIME fields are not valid!  
COMMENTS:        SC will immediately slew to this target.  
COMMENTS:        This does not match any source in the ground catalog.
