TRIGGER_INDEX:   20000
RATE_SIGNIF:     0.00 [sigma]
IMAGE_SIGNIF:    6.67 [sigma]
FLAGS:           0x3
MERIT:           76.00

SUN_DIST:        123.77 [deg]   Sun_angle= -10.5 [hr] (East of Sun)
MOON_POSTN:      255.16d {+17h 00m 39s}  -21.96d {-21d 57' 39"}
MOON_DIST:        65.16 [deg]

GAL_COORDS:      295.53, -0.02 [deg] galactic lon,lat of the burst (or transient)
ECL_COORDS:      214.96,-55.07 [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: 1E1145.1-6141,   delta=0.036 [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 = 99.94,-18.13 [deg].
