TRIGGER_INDEX:   0
RATE_SIGNIF:     0.00 [sigma]
IMAGE_SIGNIF:    0.00 [sigma]
FLAGS:           0x3
MERIT:           95.00
SUN_POSTN:       199.37d {+13h 17m 28s}   -8.18d {-08d 10' 50"}
SUN_DIST:        138.95 [deg]   Sun_angle= 10.1 [hr] (West of Sun)
MOON_POSTN:        6.69d {+00h 26m 45s}   +7.21d {+07d 12' 24"}

GAL_COORDS:      148.98,-14.90 [deg] galactic lon,lat of the burst (or transient)
ECL_COORDS:       56.17, 22.43 [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 matches a source in the ground catalog: Algol,   delta=0.002 [deg].  
COMMENTS:        There is a bright star (mag=2.12) 0.64 arcmin from this position.
