COMMENTS:        SWIFT-BAT GRB Coordinates.  
COMMENTS:        This is an image trigger.  (The RATE_SIGNIF & BKG_{INTEN, TIME, DUR} are undefined.)  
COMMENTS:        A point_source was found.  
COMMENTS:        This matches a source in the on-board catalog: Num=15360=(null) (probably an AT_Slot).  
COMMENTS:        This matches a source in the ground catalog: 1E_1742.5-2859,   delta=0.121 [deg].  
COMMENTS:        This is not a GRB.  
COMMENTS:        This trigger occurred at longitude,latitude = 135.55,13.28 [deg].  
COMMENTS:           
COMMENTS:        This trigger occured while the StarTracker had lost lock, so it is possibly bogus.
