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:           
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 does not match any source in the on-board catalog.  
COMMENTS:        This is a GRB.  
COMMENTS:        This trigger occurred at longitude,latitude = 288.34,1.37 [deg].
