COMMENTS:        WARNING: XRT alignment calibration is on-going, and there may be  
COMMENTS:        residual systematic offsets of several arcseconds not accounted for yet  
COMMENTS:        by our on-board position determination algorithm.  We have increased  
COMMENTS:        the estimated error circle radius to take this into account.  
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 example at:
