COMMENTS:        The XRT position is 2.66 arcmin from the BAT position.  
COMMENTS:        There is a bright star (mag=5.71) 8.22 arcmin from the XRT position.  
COMMENTS:        The object found at this position is either a very bright burst or a cosmic ray hit.  
COMMENTS:        Examine the XRT Image to differentiate (CRs are much more compact); see examples at:
