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: IGRJ16418-4532,   delta=0.033 [deg].  
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 = 242.01,-15.95 [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.
