The power law index is -0.83 (+0.38/-0.30) and\nthe cutoff energy, parameterized as Epeak, is 330 (+402/-150) keV\n(CSTAT  509 for 488 d.o.f.).\n\nThe event fluence (10-1000 keV) in this time interval is\n(2.4 +/- 0.5)E-07 erg/cm^2. The 64 ms peak photon flux measured\nstarting from T0-0.064 s in the 10-1000 keV band\nis 5.40 +/- 0.82 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
