COMMENTS:        SWIFT SC Slew decision.  
COMMENTS:        SC will NOT slew immediately to this target; Earth_limb constraint.  
COMMENTS:        There maybe a delayed slew or no slew at all; see WAIT_TIME.  
COMMENTS:        This does not match any source in the ground catalog.  
COMMENTS:        There is a bright star (mag=0.00) 0.00 arcmin from this position.  
COMMENTS:           
COMMENTS:        The next comments were copied from the BAT_POS Notice:  
COMMENTS:        This is a rate trigger.  
COMMENTS:        A point_source was not found.  
COMMENTS:        This matches a source that was purposefully removed from the on-board catalog.  
COMMENTS:        This is not a GRB.  
COMMENTS:        This trigger occurred during a high background rate interval.  
COMMENTS:           
COMMENTS:        The IMAGE_SIGNIF is VERY LOW, this is very likely not real.  
COMMENTS:        Since the foreground interval count rate is less than the bkg interval (SAA exit), this is a questionable detection.  
COMMENTS:        This trigger occurred at longitude,latitude = 112.49,-15.94 [deg].  
COMMENTS:           
COMMENTS:        This trigger occured while the StarTracker had lost lock, so it is possibly bogus.
