COMMENTS: SWIFT SC Slew decision.
COMMENTS: SC will NOT slew immediately to this target; Earth_limb constraint.
COMMENTS: There maybe a delayed slew or no slew at all; see WAIT_TIME.
COMMENTS: This does not match any source in the ground catalog.
COMMENTS:
COMMENTS: The next comments were copied from the BAT_POS Notice:
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 is a GRB.
COMMENTS: This trigger occurred during a high background rate interval.
COMMENTS: Since the BAT IMAGE_SIGNIF is less than 7 sigma, this is a questionable detection.
COMMENTS: This trigger occurred at longitude,latitude = 276.64,-16.46 [deg].
