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: This matches a source in the ground catalog: 4U_1901+03, delta=0.067 [deg].
COMMENTS: There is a bright star (mag=6.73) 6.90 arcmin from this position.
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:
COMMENTS: The IMAGE_SIGNIF is VERY LOW, this is very likely not real.
COMMENTS: This trigger occurred at longitude,latitude = 260.96,6.18 [deg].
