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 does not match any source in the on-board catalog.  
COMMENTS:        This does not match any source in the ground catalog.  
COMMENTS:        This is not a GRB.  
COMMENTS:           
COMMENTS:        This is a RETRACTION of a previous notice that identified this as a GRB -- it is NOT a GRB.  
COMMENTS:           
COMMENTS:        This trigger occured while the StarTracker had lost lock, so it is possibly bogus.  
COMMENTS:        This Notice was ground-reprocessed from flight-data.  
COMMENTS:          
COMMENTS:        This is NOT a GRB or anything astrophysical.  
COMMENTS:        This trigger was caused by a StarTracker loss-of-lock.
