GAL_COORDS: 28.13, -0.66 [deg] galactic lon,lat of the burst (or transient)
ECL_COORDS: 281.84, 18.40 [deg] ecliptic lon,lat of the burst (or transient)
COMMENTS: SWIFT Figure-of-Merit decision.
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: IGR18450-0435, delta=0.011 [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: This is an interesting source.
COMMENTS: Since the IMAGE_SIGNIF is less than 7 sigma, this is a questionable detection.
COMMENTS: This trigger occurred at longitude,latitude = 258.58,1.86 [deg].
