TRIGGER_INDEX:   20000
RATE_SIGNIF:     0.00 [sigma]
IMAGE_SIGNIF:    6.99 [sigma]
FLAGS:           0x3
MERIT:           98.39

SUN_DIST:        160.90 [deg]   Sun_angle= 11.7 [hr] (West of Sun)
MOON_POSTN:      171.63d {+11h 26m 31s}   -0.83d {-00d 49' 31"}
MOON_DIST:       109.62 [deg]
MOON_ILLUM:      38 [%]
GAL_COORDS:       28.13, -0.66 [deg] galactic lon,lat of the burst (or transient)
ECL_COORDS:      281.84, 18.40 [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: IGR18450-0435,   delta=0.011 [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:        This is an interesting source.  
COMMENTS:        Since the IMAGE_SIGNIF is less than 7 sigma, this is a questionable detection.  
COMMENTS:        This trigger occurred at longitude,latitude = 258.58,1.86 [deg].
