COMMENTS: SWIFT Figure-of-Merit decision.
COMMENTS:
COMMENTS: WARNING: No BAT_Position TDRSS message was received for this trigger_number!
COMMENTS:
COMMENTS: Because no BAT_Position Notice was received, this FOM Notice was forced out after watchdog expiration.
COMMENTS: This was of sufficient merit to become the new Automated Target;
COMMENTS: but if the Current PPT has a greater merit, then we will not request a slew.
COMMENTS: FOM will request the s/c to slew.
COMMENTS: The S/C has yet to make its decision about safe to slew or not.
COMMENTS: This matches a source in the ground catalog: IGR16418-4532, delta=0.030 [deg].
COMMENTS:
COMMENTS: The next comments were copied from the BAT_POS Notice:
COMMENTS: This is an image trigger. (The RATE_SIGNIF is undefined.)
COMMENTS: A point_source was found.
COMMENTS: This matches a source in the on-board catalog.
COMMENTS: This is not a GRB.
COMMENTS:
COMMENTS: The IMAGE_SIGNIF is VERY LOW, this is very likely not real.
COMMENTS: This trigger occurred at longitude,latitude = 88.91,-18.11 [deg].
