COMMENTS:        SWIFT SC Slew decision.  
COMMENTS:        SC will immediately slew to this target.  
COMMENTS:        This matches a source in the ground catalog: NGC4310,   delta=0.084 [deg].  
COMMENTS:        Galaxy NGC4310 (of total mag=13.00 and dia=2.60 arcmin) is inside the position error circle.  
COMMENTS:        There is a 0.09% probability that an NGC galaxy would happen by chance coincidence.  
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 matches a source in the on-board catalog.  
COMMENTS:        This is not a GRB.  
COMMENTS:        This is an interesting source.  
COMMENTS:           
COMMENTS:        The IMAGE_SIGNIF is VERY LOW, this is very likely not real.  
COMMENTS:        This trigger occurred at longitude,latitude = 67.31,3.88 [deg].
