COMMENTS: SWIFT-XRT Coordinates.
COMMENTS: This matches a source in the BAT ground catalog: GX_17+2, delta=0.004 [deg].
COMMENTS: The XRT position is 1.37 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:
