COMMENTS:        SWIFT-BAT Sub-Threshold GRB Coordinates.  
COMMENTS:        This Notice was delayed by more than 60 sec past the end of the trigger integration interval;  
COMMENTS:        probably due to it occurring during a Malindi downlink session.  
COMMENTS:        This Notice is generated as a result of an uploaded TOO -- this is not a normal BAT-detected burst.  
COMMENTS:        As a result of this TOO, only the GRB_RA/_DEC, SUN, MOON, and GAL_/ECL_COORDS fields will be valid!  
COMMENTS:        This Notice was originally generated with the GRB_DATE & GRB_TIME fields set to zero,  
COMMENTS:        so those fields are now filled using the spacecraft system clock (not the normal burst trigger_time).  
COMMENTS:        This is usually the result of an uploaded GRB_TOO -- this is not a normal BAT-detected burst.  
COMMENTS:        This is a rate trigger.  
COMMENTS:        A point_source was not 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 a TOO.  
COMMENTS:           
COMMENTS:        The IMAGE_SIGNIF is VERY LOW, this is very likely not real.  
COMMENTS:        This trigger occurred at longitude,latitude = 17.79,-20.02 [deg].
