The revised mask-weighted light curve\nstarts before T-200 sec (where we start collecting event data\non each trigger), slowly rises to a peak around T+400 sec\nand slowly decreases to a minumum around T+1100 sec, then increases\nto a second maximum around T+1650 sec, and then decreases again\nwith continuing emission past T+2100 sec (where the data stops).\nThe amplitudes of the two peaks are 0.09 +- 0.01 and 0.060 +- 0.006\nph/cm2/sec, resp.",
