COMMENTS: SWIFT-XRT Coordinates.
COMMENTS: This matches a source in the BAT ground catalog: HD 8357, delta=0.001 [deg].
COMMENTS: The XRT position is 3.25 arcmin from the BAT 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:
