COMMENTS: SWIFT SC Slew decision.
COMMENTS: SC will immediately slew to this target.
COMMENTS: This matches a source in the ground catalog: NGC4487, delta=0.083 [deg].
COMMENTS: Galaxy NGC4487 (of total mag=11.00 and dia=4.10 arcmin) is inside the position error circle.
COMMENTS: There is a 0.09% probability that an NGC galaxy would happen by chance coincidence.
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 = 93.01,16.48 [deg].
