MOON_POSTN:      257.10d {+17h 08m 24s}  -27.62d {-27d 37' 21"}
MOON_DIST:        32.57 [deg]
MOON_ILLUM:      10 [%]
GAL_COORDS:       28.08, -0.67 [deg] galactic lon,lat of the pointing direction
ECL_COORDS:      281.81, 18.35 [deg] ecliptic lon,lat of the pointing direction
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:        This matches a source in the ground catalog: IGR18450-0435,   delta=0.043 [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 is an interesting source.  
COMMENTS:        This trigger occured while the StarTracker had lost lock, so it is probably bogus.
