COMMENTS: SWIFT Figure-of-Merit decision.
COMMENTS: This was NOT of sufficient merit to become the new Automated Target.
COMMENTS: FOM will NOT request the s/c to slew.
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: Since the IMAGE_SIGNIF is less than 7 sigma, this is a questionable detection.
COMMENTS: This trigger occurred at longitude,latitude = 21.50,17.55 [deg].
