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: There is a bright star (mag=5.95) 4.20 arcmin from this position.
