COMMENTS: SWIFT-BAT GRB Coordinates.
COMMENTS: This is a rate trigger.
COMMENTS: A point_source was found.
COMMENTS: This does not match any source in the on-board catalog.
COMMENTS: This does not match any source in the ground catalog.
COMMENTS: This is not a GRB.
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: With humans-in-the-loop ground analysis,
COMMENTS: this is NOT a GRB (nor a transient).
COMMENTS: This trigger was due to a cosmic ray shower in the instrument.
