COMMENTS: SWIFT-BAT GRB Lightcurve.
COMMENTS:
COMMENTS: The next comments were copied from the BAT_POS Notice:
COMMENTS: This is an image trigger.
COMMENTS: A point_source was found.
COMMENTS: This matches a source in the on-board catalog.
COMMENTS: This matches a source in the ground catalog: AX_1631.9-4752, delta=0.090 [deg].
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 = 72.86,-7.18 [deg].
COMMENTS: This lightcurve contains more than 50 illegal values -- probably an empty lightcurve.
COMMENTS: So the FITS file will have empty/missing rows -- possibly all rows will be missing.
COMMENTS: One explanation is a long Image-trigger(>~10min); another is corrupted tlm.
