TRIGGER_INDEX:   20000
RATE_SIGNIF:     0.00 [sigma]
IMAGE_SIGNIF:    6.50 [sigma]
FLAGS:           0x3
MERIT:           98.39
SUN_POSTN:        14.42d {+00h 57m 40s}   +6.16d {+06d 09' 33"}
SUN_DIST:        108.16 [deg]   Sun_angle= 7.1 [hr] (West of Sun)
MOON_POSTN:      208.21d {+13h 52m 50s}   -9.72d {-09d 43' 12"}
MOON_DIST:        57.91 [deg]
MOON_ILLUM:      99 [%]
GAL_COORDS:        3.84,  1.71 [deg] galactic lon,lat of the burst (or transient)
ECL_COORDS:      267.28, -1.36 [deg] ecliptic 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 matches a source in the ground catalog: Terzan_5,   delta=0.020 [deg].  
COMMENTS:           
COMMENTS:        The next comments were copied from the BAT_POS Notice:  
COMMENTS:        This is an image trigger.  (The RATE_SIGNIF is undefined.)  
COMMENTS:        A point_source was found.  
COMMENTS:        This matches a source in the on-board catalog.  
COMMENTS:        This is not a GRB.  
COMMENTS:        Since the IMAGE_SIGNIF is less than 7 sigma, this is a questionable detection.  
COMMENTS:        This trigger occurred at longitude,latitude = 96.27,-13.94 [deg].
