COMMENTS: SWIFT-BAT GRB Coordinates.
COMMENTS: This is a rate trigger.
COMMENTS: A point_source was found.
COMMENTS: This matches a source in the on-board catalog.
COMMENTS: This does not match any source in the ground catalog.
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: SWIFT-BAT GRB Coordinates.
COMMENTS: This is a rate trigger.
COMMENTS: A point_source was found.
COMMENTS: This matches a source in the on-board catalog.

COMMENTS: This trigger occurred at longitude,latitude =
COMMENTS: This is not a real GRB or transient, but a chance
COMMENTS: a rate increase and a noise fluctuation in the image
COMMENTS: was in proximity to, but not at a known source.
