The power law index is -1.23 +/- 0.06 and\nthe cutoff energy, parameterized as Epeak, is 280 +/- 40 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(3.2 +/- 0.2)E-5 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+190.7 s in the 10-1000 keV band\nis 5.7 +/- 0.2 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
