The time-averaged spectrum from T0-2.048 s to T0+9.216 s is\nwell fit by a power law function with an exponential high-energy cutoff. \nThe power law index is -1.38 +/- 0.15 and the cutoff energy, \nparameterized as Epeak, is 85.0 +/- 14.4  keV\n\nThe event fluence (10-1000 keV) in this time interval is\n(1.5 +/- 1.4)E-06  erg/cm^2. The 1.024-sec peak photon flux measured\nstarting from T0+3.71204 s in the 10-1000 keV band\nis 4.7 +/- 0.3 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
