The power law index is -0.56 +/- 0.14 and\nthe cutoff energy, parameterized as Epeak, is 503 +/- 91 keV\n(chi squared 327 for 358 d.o.f.).\n\nThe event fluence (8-1000 keV) in this time interval is\n(5.7 +/- 0.3)E-06 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+2.8 s in the 8-1000 keV band\nis 3.62 +/- 0.17 ph/s/cm^2.\n\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
