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 matches a source in the ground catalog: Sco_X-1,   delta=0.205 [deg].  
COMMENTS:        This is not a GRB.  
COMMENTS:        This trigger occurred at longitude,latitude = 129.71,-14.21 [deg].  
COMMENTS:           
COMMENTS:        This trigger occured while the StarTracker had lost lock, so it is possibly bogus.
