COMMENTS: SWIFT-BAT GRB Coordinates.
COMMENTS: This is an image trigger. (The RATE_SIGNIF & BKG_{INTEN, TIME, DUR} are undefined.)
COMMENTS: A point_source was found.
COMMENTS: This matches a source in the on-board catalog.
COMMENTS: This matches a source in the ground catalog: X 1832-330, delta=0.137 [deg].
COMMENTS: This is not a GRB.
COMMENTS: This is an interesting source.
COMMENTS: Since the IMAGE_SIGNIF is less than 7 sigma, this is a questionable detection.
COMMENTS: This is a RETRACTION of a previous notice that identified this as a GRB -- it is NOT a GRB.
COMMENTS: This Notice was ground-reprocessed from flight-data.
COMMENTS:
COMMENTS: This is NOT a Transient nor is it a GRB.
COMMENTS: This is a chance coincidence of a fluctuation in the image domain and a known source location.
